INA134UA/2K5G4

Overview

The INA134UA/2K5G4 is a single-channel differential line receiver manufactured by Texas Instruments. It integrates a high-performance operational amplifier with on-board precision laser-trimmed resistors to provide a fixed unity gain of 0dB (1V/V). The device operates within a wide supply voltage range of ±4V to ±18V, supporting total supplies from 8V to 36V. It features low distortion and high slew rate capabilities, housed in an 8-pin SOIC surface-mount package.

Feature Summary

• Integrates high-performance operational amplifier with on-chip precision laser-adjusted resistors for accurate gain and optimal common-mode rejection.
• Provides fixed unity gain configuration suitable for differential signal processing without external feedback components.
• Delivers high slew rate and fast settling time to ensure excellent dynamic response in audio applications.

Applications

• Audio differential line receivers
• Ground loop eliminators
• Summing amplifiers
• Current shunt monitors

Procurement Notes

Verify the specific suffix G4 against current manufacturer documentation to confirm compliance status and revision history. Ensure the ordering part number matches the required package type and temperature rating. Confirm availability through authorized distributors as lead times may vary based on production cycles.

Selection Notes

Select this component for applications requiring precise differential-to-single-ended conversion with minimal external parts. The integrated resistor network simplifies design while maintaining high common-mode rejection ratios. Consider the wide supply voltage range when designing power systems for industrial or professional audio environments.

Part Context

This device belongs to the INA134 series of audio line drivers and receivers. It is designed specifically for high-fidelity audio applications where low distortion and high dynamic range are critical. The integration of precision resistors distinguishes it from standard operational amplifiers that require external matching networks.
