INA137UAG4

Overview

The INA137UAG4 is a high-precision, wide-bandwidth difference amplifier manufactured by Texas Instruments. It features an e-trim architecture for enhanced accuracy and stability. The device operates within a supply voltage range of 5 V to 36 V and supports dual supplies from 2.5 V to 18 V. It utilizes a SOIC-8 surface-mount package suitable for automated assembly. The component functions as a differential line receiver with selectable gain configurations.

Feature Summary

• Integrated e-trim technology ensures high precision and long-term stability without external calibration.
• Wide bandwidth capability supports high-speed signal processing applications.
• Configurable gain settings allow flexible implementation in differential line receiving circuits.

Applications

• Audio differential line receivers
• High-precision signal conditioning
• Industrial data acquisition systems

Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's current datasheet to confirm RoHS compliance status and lead time requirements. Confirm that the SOIC-8 package matches your PCB footprint design. Check for any obsolescence notices or lifecycle changes directly from Texas Instruments before finalizing procurement plans.

Selection Notes

Select this component when a fixed-gain difference amplifier with high common-mode rejection is required. Ensure the input common-mode voltage range aligns with your system's signal levels. Verify that the single-supply or dual-supply operation fits your power budget constraints.

Part Context

This part belongs to the INA137 family of difference amplifiers designed for audio and instrumentation applications. It replaces older discrete resistor networks by providing integrated precision matching. The UAG4 designation indicates a specific tape-and-reel or tube packaging variant within the standard industrial temperature range.

Replacement Considerations

Direct pin-compatible substitutes include other e-trim difference amplifiers from the same family. Verify gain accuracy and bandwidth specifications match the original design requirements before substitution.
