TLV2372IPG4 Equivalent & Substitute Parts

Part Overview

The TLV2372IPG4 is a general-purpose operational amplifier featuring dual circuits in an 8-PDIP through-hole package. This device delivers rail-to-rail output capability with a 3 MHz gain-bandwidth product and operates across a 2.7 V to 16 V supply range. The TLV2372IPG4 is classified as obsolete, necessitating identification of active equivalent components for new designs and ongoing production requirements. Substitute parts must maintain functional compatibility across electrical specifications and physical packaging to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV2372IPG4 is determined by strict alignment of electrical and mechanical parameters. The primary substitution criteria are:

Mandatory Matching Parameters:

• Dual-circuit configuration (2 circuits)
• Rail-to-rail output capability
• 8-PDIP through-hole package format (0.300", 7.62mm)
• Supply voltage range compatibility (minimum 2.7 V, maximum 16 V)
• Operating temperature range support

Performance Tolerance Parameters: Substitute parts may exhibit variations in slew rate, gain-bandwidth product, input offset voltage, and supply current, provided these variations do not degrade system performance in the target application. The TLV2372IP represents a direct equivalent with identical electrical specifications and active product status. The ICL7621BCPA+ and ICL7621DCPA+ are CMOS-based alternatives that maintain package compatibility and dual-circuit architecture but operate with reduced slew rate (1.6 V/µs) and gain-bandwidth product (1.4 MHz), with restricted operating temperature range (0°C to 70°C).

Parameter Comparison

Engineering Selection Recommendations

TLV2372IP (Primary Substitute)

The TLV2372IP is the recommended direct substitute for the obsolete TLV2372IPG4. This component maintains identical electrical specifications, including slew rate (2.1 V/µs), gain-bandwidth product (3 MHz), input offset voltage (2 mV), and supply current (750 µA per dual channels). The TLV2372IP carries active product status from Texas Instruments, ensuring long-term availability and supply chain continuity. Both devices are ROHS3 compliant and operate across the full -40°C to 125°C temperature range. The only distinction is packaging format: TLV2372IP is supplied in tube packaging, whereas TLV2372IPG4 was supplied in alternative packaging. Pin configuration and electrical performance are identical, enabling direct socket replacement without circuit modification.

ICL7621BCPA+ and ICL7621DCPA+ (Alternative Substitutes)

The ICL7621BCPA+ and ICL7621DCPA+ are alternative substitutes manufactured by Analog Devices Inc./Maxim Integrated. These CMOS-based dual operational amplifiers maintain the 8-DIP through-hole package format and rail-to-rail output capability. However, these alternatives exhibit reduced performance specifications: slew rate of 1.6 V/µs (versus 2.1 V/µs) and gain-bandwidth product of 1.4 MHz (versus 3 MHz). The operating temperature range is restricted to 0°C to 70°C, limiting applicability in extended-temperature environments. The ICL7621BCPA+ exhibits input offset voltage of 5 mV, while the ICL7621DCPA+ exhibits 15 mV. Supply current is increased to 1 mA per dual channels. These alternatives are suitable only for applications where reduced bandwidth and slew rate are acceptable, and where operating temperature does not fall below 0°C or exceed 70°C.

Frequently Asked Questions (FAQ)

Q: Can the TLV2372IP directly replace the TLV2372IPG4 without circuit modification?

A: Yes. The TLV2372IP is electrically and functionally identical to the TLV2372IPG4. Both devices feature identical pin configuration, electrical specifications, and performance characteristics. The difference is packaging format only. Direct socket replacement is possible without circuit redesign.

Q: What are the key differences between TLV2372IP and ICL7621BCPA+?

A: The primary differences are amplifier architecture and performance specifications. TLV2372IP is a general-purpose amplifier with 3 MHz gain-bandwidth product and 2.1 V/µs slew rate. ICL7621BCPA+ is a CMOS amplifier with 1.4 MHz gain-bandwidth product and 1.6 V/µs slew rate. TLV2372IP operates across -40°C to 125°C; ICL7621BCPA+ operates across 0°C to 70°C. TLV2372IP is the preferred substitute for applications requiring higher bandwidth and extended temperature operation.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. TLV2372IP, ICL7621BCPA+, and ICL7621DCPA+ are all ROHS3 compliant. All substitute parts meet environmental compliance requirements equivalent to the original TLV2372IPG4.

Q: Can ICL7621DCPA+ be used in applications requiring -40°C operation?

A: No. ICL7621DCPA+ is rated for 0°C to 70°C operating temperature only. Applications requiring operation below 0°C must use TLV2372IP, which is rated for -40°C to 125°C.

Q: What is the impact of reduced slew rate in ICL7621 alternatives?

A: Reduced slew rate (1.6 V/µs versus 2.1 V/µs) limits the maximum rate of output voltage change. This affects applications with high-frequency signals or fast transient response requirements. Applications with bandwidth requirements below 1.4 MHz may tolerate this reduction; higher-bandwidth applications require TLV2372IP.

Q: Are the 8-DIP packages physically identical across all substitute parts?

A: Yes. All substitute parts use 8-DIP (0.300", 7.62mm) through-hole packages with identical pin spacing and physical dimensions. PCB footprints are interchangeable across all listed substitutes.

Q: What is the significance of input offset voltage differences between ICL7621BCPA+ and ICL7621DCPA+?

A: ICL7621BCPA+ exhibits 5 mV input offset voltage; ICL7621DCPA+ exhibits 15 mV. Applications requiring precision DC amplification or low-offset performance should use ICL7621BCPA+ or TLV2372IP (2 mV offset). High-offset applications may tolerate ICL7621DCPA+.
