TS27L2IPT CMOS Amplifier Equivalent & Substitute Parts

Part Overview

The TS27L2IPT is a CMOS amplifier integrated circuit manufactured by STMicroelectronics, configured as a dual-channel operational amplifier in an 8-TSSOP surface mount package. This device is classified as a linear amplifier with active product status and full RoHS3 compliance. The TS27L2IPT is characterized by ultra-low input bias current (1 pA), low input offset voltage (1.1 mV), and low supply current consumption (10 µA per channel), making it suitable for low-power analog signal conditioning applications.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design specifications allow for performance variations within acceptable operating parameters. Substitute parts must maintain compatibility across package type, pin configuration, and critical electrical specifications to ensure direct replacement capability.

Performance Parameter Ranges: Substitute parts are grouped into three performance categories based on slew rate and gain bandwidth product specifications:

Ultra-Low Power Category (Slew Rate ≤ 0.04 V/µs, GBW ≤ 110 kHz): Parts optimized for minimal power consumption with reduced bandwidth performance.
Mid-Range Performance Category (Slew Rate 0.62 V/µs, GBW = 635 kHz): Parts offering moderate speed and power consumption balance.
High-Speed Category (Slew Rate ≥ 2.9 V/µs, GBW ≥ 2.2 MHz): Parts designed for faster signal processing with higher current requirements.

Substitution within categories is permissible when application requirements allow for performance variations. Cross-category substitution requires design verification to confirm compatibility with circuit bandwidth and slew rate requirements.

Engineering Selection Recommendations

Primary Substitute: TLC27L2CPWR

The TLC27L2CPWR is the closest functional equivalent to the TS27L2IPT. Both devices operate in the ultra-low power category with slew rates below 0.04 V/µs and gain bandwidth products near 100 kHz. The TLC27L2CPWR maintains identical input offset voltage (1.1 mV), supply voltage range (3 V to 16 V), and 8-TSSOP package configuration. The primary difference is the operating temperature range (0°C to 70°C versus -40°C to 125°C), which restricts use in extended temperature applications. The TLC27L2CPWR carries Active product status with full RoHS3 compliance and is available in Cut Tape & Digi-Reel® packaging format.

Secondary Substitute: TLC27L2IPW

The TLC27L2IPW provides identical electrical performance to the TLC27L2CPWR with extended operating temperature range (-40°C to 85°C), making it suitable for applications requiring lower temperature operation. This part carries Last Time Buy status, indicating limited future availability. The TLC27L2IPW is supplied in Tube packaging format rather than Tape & Reel.

Alternative for Mid-Range Performance: TLC27M2IPWR

The TLC27M2IPWR operates in the mid-range performance category with slew rate of 0.62 V/µs and gain bandwidth product of 635 kHz. This device is suitable for applications requiring faster signal processing than the ultra-low power category. The TLC27M2IPWR maintains the extended operating temperature range (-40°C to 85°C) and carries Active product status. Supply current consumption increases to 285 µA per channel, representing a 28.5-fold increase compared to the TS27L2IPT.

Alternative for High-Speed Applications: TLC272CPWR

The TLC272CPWR operates in the high-speed category with slew rate of 5.3 V/µs and gain bandwidth product of 2.2 MHz. This device is appropriate for applications requiring significantly faster bandwidth performance. The TLC272CPWR operates at reduced temperature range (0°C to 70°C) and carries Active product status. Supply current consumption is 1.9 mA per channel, representing a 190-fold increase compared to the TS27L2IPT.

Compliance and Availability Considerations:

All substitute parts maintain RoHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard surface mount assembly processes. The TS27L2IPT maintains the widest operating temperature range (-40°C to 125°C) among all listed alternatives. Selection of substitute parts with narrower temperature ranges requires verification that application operating conditions remain within specified limits. Parts with Last Time Buy status (TLC27L2IPW, TLC27M2CPW, TLC252CPWR) have limited future procurement availability and should be considered only when Active alternatives are unsuitable.

Frequently Asked Questions (FAQ)

Q: Can the TLC27L2CPWR directly replace the TS27L2IPT in all applications?

A: The TLC27L2CPWR is electrically compatible with the TS27L2IPT for applications operating within the 0°C to 70°C temperature range. Both devices share identical slew rate (0.04 V/µs), gain bandwidth product (100 kHz), input offset voltage (1.1 mV), and 8-TSSOP package configuration. Applications requiring operation below 0°C or above 70°C require alternative parts with extended temperature ratings.

Q: What is the difference between the TLC27L2CPWR and TLC27L2IPW?

A: Both parts are functionally identical with matching electrical specifications. The primary difference is the operating temperature range: TLC27L2CPWR operates from 0°C to 70°C, while TLC27L2IPW operates from -40°C to 85°C. The TLC27L2IPW is supplied in Tube packaging, whereas the TLC27L2CPWR is supplied in Cut Tape & Digi-Reel® format. The TLC27L2IPW carries Last Time Buy status, indicating limited future availability.

Q: When should I use the TLC27M2IPWR instead of the TLC27L2CPWR?

A: The TLC27M2IPWR is selected when application bandwidth requirements exceed 110 kHz. The TLC27M2IPWR provides 635 kHz gain bandwidth product and 0.62 V/µs slew rate, enabling faster signal processing. This performance increase requires higher supply current consumption (285 µA per channel versus 20 µA per channel). The TLC27M2IPWR maintains extended operating temperature range (-40°C to 85°C) and Active product status.

Q: Is the TLC272CPWR suitable as a substitute for the TS27L2IPT?

A: The TLC272CPWR is electrically compatible at the package and pin level but operates in a different performance category. The TLC272CPWR provides 2.2 MHz gain bandwidth product and 5.3 V/µs slew rate, representing 22-fold higher bandwidth than the TS27L2IPT. Supply current consumption increases to 1.9 mA per channel. The TLC272CPWR is appropriate only for applications where higher bandwidth performance is required and the increased power consumption is acceptable. Operating temperature range is limited to 0°C to 70°C.

Q: What packaging formats are available for substitute parts?

A: Substitute parts are available in multiple packaging formats: Tape & Reel (TR) for automated assembly processes, Cut Tape (CT) & Digi-Reel® for mixed-volume production, and Tube for manual assembly or lower-volume applications. The TS27L2IPT is supplied in Tape & Reel format. Packaging format selection depends on manufacturing process requirements and production volume.

Q: Are all substitute parts RoHS3 compliant?

A: All substitute parts listed carry RoHS3 compliance certification and MSL Level 1 rating. These certifications ensure compatibility with standard surface mount assembly processes and environmental regulations. The TS27L2IPT also maintains full RoHS3 compliance and MSL Level 1 rating.

Q: What does "Last Time Buy" product status mean?

A: Last Time Buy status indicates that the manufacturer has announced end-of-life for the part and will accept orders only until a specified cutoff date. After this date, the part will no longer be available for purchase. Parts with Last Time Buy status (TLC27L2IPW, TLC27M2CPW, TLC252CPWR) should be considered only when Active alternatives are unsuitable for the application. Long-term designs should prioritize parts with Active status.

Q: Can I substitute a part with higher supply current consumption in a battery-powered application?

A: Supply current consumption directly impacts battery life and thermal management in battery-powered applications. The TS27L2IPT operates at 10 µA per channel, while higher-performance alternatives consume 20 µA to 1.9 mA per channel. Substitution with higher current consumption parts requires verification that power budget and thermal constraints remain acceptable. Ultra-low power applications should prioritize the TS27L2IPT or TLC27L2 series parts.

Q: What is the significance of the input bias current specification?

A: Input bias current affects circuit accuracy in high-impedance signal conditioning applications. The TS27L2IPT specifies 1 pA input bias current, while substitute parts range from 0.6 pA to 0.7 pA. These differences are negligible for most applications. High-impedance circuits (>1 MΩ) may require verification that input bias current remains within acceptable limits for the specific application.
