TLV2372IDRG4 Equivalent & Substitute Parts

Part Overview

The TLV2372IDRG4 is a general-purpose operational amplifier featuring dual circuits in a rail-to-rail output configuration, manufactured by Texas Instruments in an 8-SOIC surface mount package. This device is classified as obsolete, necessitating identification of equivalent and substitute components for ongoing design support and procurement continuity. The part operates across a supply voltage range of 2.7V to 16V with a slew rate of 2.1V/µs and gain bandwidth product of 3 MHz, making it suitable for low-power analog signal processing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV2372IDRG4 is determined by strict equivalence across the following critical parameters:

Package Compatibility: All substitute parts must use the 8-SOIC surface mount package with identical 0.154" (3.90mm) width to ensure PCB footprint compatibility without layout modifications.

Functional Configuration: Substitute parts must provide dual-circuit (2 circuits) operational amplifier functionality with rail-to-rail output capability to maintain signal swing characteristics in the application.

Supply Voltage Range: The substitute must operate within the specified supply voltage span of 2.7V minimum to 16V maximum. Parts with narrower supply ranges are not acceptable substitutes.

Operating Temperature Range: Substitute parts must support the full -40°C to 125°C operating temperature range to ensure reliability across the intended application environment.

Electrical Performance Envelope: While exact parameter matching is not required, substitute parts must not introduce incompatibilities in slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, or output current that would degrade circuit performance or violate design margins.

Compliance Requirements: All substitute parts must maintain ROHS3 compliance and MSL 1 rating to ensure regulatory and manufacturing process compatibility.

Parameter Comparison

Engineering Selection Recommendations

TLV2372IDR (Primary Substitute): This part is the direct equivalent to the TLV2372IDRG4, manufactured by Texas Instruments with identical electrical specifications, package configuration, and supply voltage range. The TLV2372IDR maintains active product status, ensuring long-term availability and manufacturing support. This substitute provides complete functional and electrical compatibility with no design modifications required. The only difference is packaging format (Cut Tape & Digi-Reel versus the original Digi-Reel specification), which does not affect circuit performance or PCB assembly compatibility.

ADA4665-2ARZ (Secondary Substitute): This Analog Devices part provides functional substitution with the same dual-circuit, rail-to-rail 8-SOIC configuration and full operating temperature range. However, this substitute introduces the following electrical differences: reduced slew rate (1V/µs versus 2.1V/µs), lower gain bandwidth product (1.2 MHz versus 3 MHz), lower supply current (290µA versus 750µA), and higher output current capability (30mA versus 16mA). The minimum supply voltage requirement is 5V, which is higher than the TLV2372IDRG4's 2.7V minimum. The ADA4665-2ARZ is suitable only for applications where the reduced bandwidth and slew rate are acceptable, and where the 5V minimum supply voltage does not conflict with system design requirements.

Product Status Consideration: The TLV2372IDR is the recommended substitute due to its active product status and complete electrical equivalence. The ADA4665-2ARZ, while active and available, introduces performance trade-offs that require circuit-level evaluation before implementation.

Frequently Asked Questions (FAQ)

Q: Can the TLV2372IDR be used as a direct replacement for the TLV2372IDRG4 without PCB modifications?

A: Yes. The TLV2372IDR is electrically and mechanically identical to the TLV2372IDRG4. Both parts use the 8-SOIC package with 0.154" (3.90mm) width, identical pin configuration, and matching electrical specifications. No PCB layout changes are required.

Q: What is the key difference between TLV2372IDR and ADA4665-2ARZ?

A: The TLV2372IDR is a direct equivalent with identical slew rate (2.1V/µs) and gain bandwidth product (3 MHz). The ADA4665-2ARZ has reduced slew rate (1V/µs) and bandwidth (1.2 MHz), but lower supply current consumption (290µA versus 750µA) and higher output current (30mA versus 16mA). Additionally, the ADA4665-2ARZ requires a minimum 5V supply, whereas the TLV2372IDRG4 operates from 2.7V.

Q: Is the ADA4665-2ARZ suitable for all applications using the TLV2372IDRG4?

A: No. The ADA4665-2ARZ is suitable only for applications where reduced bandwidth and slew rate do not degrade performance, and where the 5V minimum supply voltage is compatible with system design. Applications requiring the full 3 MHz bandwidth or operation below 5V supply voltage must use the TLV2372IDR.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. Both the TLV2372IDR and ADA4665-2ARZ are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the TLV2372IDRG4.

Q: What is the packaging difference between TLV2372IDRG4 and TLV2372IDR?

A: The TLV2372IDRG4 is supplied in Digi-Reel packaging, while the TLV2372IDR is available in Cut Tape (CT) & Digi-Reel formats. Both formats contain identical die and lead frame; the difference is in tape and reel configuration for automated assembly. This does not affect electrical performance or PCB compatibility.

Q: Can the TLV2372IDR be used in applications requiring operation below 5V?

A: Yes. The TLV2372IDR operates from 2.7V minimum supply voltage, making it suitable for low-voltage applications. The ADA4665-2ARZ requires a 5V minimum supply and is not suitable for sub-5V operation.

Q: Are there any thermal or reliability differences between the substitute parts?

A: Both substitute parts support the full -40°C to 125°C operating temperature range with MSL 1 rating. No thermal or reliability differences are specified in the provided parameters.
