INA2134UA

Overview

The INA2134UA is a dual-channel differential line receiver manufactured by Texas Instruments, housed in an 8-pin SOIC package. It operates with a supply voltage range of 8 V to 36 V and supports single or dual power configurations. The device features a fixed unity gain (G=1) for audio differential line applications. Key electrical parameters include a slew rate of 14 V/µs, a quiescent current of 2.4 mA, and a minimum common-mode rejection ratio of 86 dB. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Provides balanced-to-unbalanced conversion for audio signals with a fixed unity gain configuration.
• Integrates FET input stages to ensure high input impedance and low bias current.
• Delivers high common-mode rejection to suppress noise in differential audio lines.

Applications

• Audio differential line receivers
• Balanced-to-unbalanced signal conversion
• Professional audio equipment interfaces

Procurement Notes

Verify the specific suffix against the manufacturer datasheet to confirm packaging and compliance status. Ensure the selected variant matches the required operating temperature range and supply voltage specifications. Cross-reference the component marking with official documentation to prevent counterfeit substitution during sourcing.

Selection Notes

Select this component when a fixed unity gain differential receiver is required for professional audio systems. It is suitable for designs needing high common-mode rejection without external gain setting resistors. Consider the SOIC-8 footprint constraints and verify that the 8 V minimum supply voltage aligns with the system power architecture.

Part Context

This device belongs to the INA2134 family of audio line receivers from Texas Instruments. It is designed specifically for high-fidelity audio applications requiring precise differential signal handling. The component complements other SoundPlus series devices by offering dedicated reception capabilities rather than amplification.
