TLC27L2IPWR Equivalent & Substitute Parts

Part Overview

The TLC27L2IPWR is a CMOS dual-channel operational amplifier manufactured by Texas Instruments in 8-TSSOP surface mount packaging. This linear amplifier IC operates across a 4V to 16V supply range and is designed for low-power applications requiring minimal input bias current. The device is Active status and RoHS3 compliant, making it suitable for modern electronic designs. Substitute parts are identified when equivalent functional performance can be achieved within the allowed electrical and mechanical parameters of the CMOS amplifier category, particularly when supply voltage compatibility, package form factor, and circuit count remain constant.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC27L2IPWR is determined by strict adherence to the following allowed parameters:

Package Compatibility: All substitute parts must use 8-TSSOP surface mount packaging with identical 0.173" (4.40mm) width to ensure PCB layout compatibility without redesign.

Circuit Count: All substitutes must contain exactly 2 operational amplifier circuits to match the dual-channel configuration.

Supply Voltage Range: Substitute parts must operate within a minimum supply voltage of 3V to 4V and maximum of 16V. The TLC27L2IPWR operates at 4V minimum; substitutes with 3V minimum supply are acceptable as they encompass the original operating range.

Amplifier Type: All substitutes must be CMOS technology to maintain electrical characteristics and noise performance within the linear amplifier category.

Mounting Type: Surface mount technology is required for all substitutes.

Compliance: All substitutes must maintain RoHS3 compliance and Active product status.

The following STMicroelectronics parts meet these criteria: TS272CPT, TS272IPT, TS27L2CPT, and TS27M2CPT. These parts differ in slew rate, gain bandwidth product, supply current, and output current specifications, but remain functionally equivalent within the allowed parameter set for CMOS dual-channel amplifiers in 8-TSSOP packaging.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts—TS272CPT, TS272IPT, TS27L2CPT, and TS27M2CPT—are manufactured by STMicroelectronics and maintain Active product status with RoHS3 compliance, ensuring long-term availability and regulatory alignment with the original TLC27L2IPWR.

TS272IPT provides the widest operating temperature range (-40°C ~ 125°C), extending beyond the TLC27L2IPWR specification and offering suitability for applications requiring extended temperature performance.

TS27L2CPT maintains the closest slew rate (0.04 V/µs) and gain bandwidth product (100 kHz) to the TLC27L2IPWR, with reduced supply current (10 µA per channel) compared to the main part, making it suitable for direct replacement in low-power, low-frequency applications.

TS272CPT and TS27M2CPT exhibit significantly higher slew rates and gain bandwidth products, indicating suitability for higher-frequency signal processing applications where the TLC27L2IPWR's performance is insufficient.

All substitute parts accept the reduced minimum supply voltage of 3V, providing design flexibility for lower-voltage system implementations while maintaining compatibility with the 4V to 16V range of the original device.

Frequently Asked Questions (FAQ)

Q: Can TS272CPT directly replace TLC27L2IPWR in all applications?

A: TS272CPT is mechanically and electrically compatible within the 8-TSSOP package and dual-channel CMOS amplifier category. However, TS272CPT exhibits a slew rate of 5.5 V/µs and gain bandwidth product of 3.5 MHz, compared to TLC27L2IPWR's 0.03 V/µs and 110 kHz. Direct replacement is valid only when the application does not depend on the lower slew rate and bandwidth characteristics of the original part.

Q: What is the key difference between TS27L2CPT and TS272CPT?

A: TS27L2CPT maintains electrical characteristics closer to TLC27L2IPWR, with slew rate of 0.04 V/µs and gain bandwidth product of 100 kHz. TS272CPT provides significantly higher performance with 5.5 V/µs slew rate and 3.5 MHz bandwidth. Selection depends on whether the application requires low-frequency, low-power operation (TS27L2CPT) or higher-speed signal processing (TS272CPT).

Q: Are all substitute parts available in the same packaging?

A: Yes. All substitute parts use 8-TSSOP surface mount packaging with 0.173" (4.40mm) width, ensuring identical PCB footprint and assembly compatibility without layout modification.

Q: What is the operating temperature consideration for substitute selection?

A: TLC27L2IPWR operates from -40°C to 85°C. TS272IPT extends this range to -40°C to 125°C, suitable for high-temperature applications. TS272CPT, TS27L2CPT, and TS27M2CPT operate from 0°C to 70°C, which is narrower than the original part and requires verification for applications requiring extended low-temperature performance.

Q: Do all substitute parts maintain the same supply current specifications?

A: No. TLC27L2IPWR draws 20 µA per channel. TS27L2CPT draws 10 µA per channel (lower power), while TS272CPT and TS272IPT draw 1 mA per channel, and TS27M2CPT draws 150 µA per channel. Supply current selection depends on power budget constraints of the application.

Q: Is RoHS3 compliance maintained across all substitute parts?

A: Yes. All substitute parts are RoHS3 compliant and maintain Active product status, ensuring regulatory compliance and long-term manufacturing support equivalent to the original TLC27L2IPWR.
