INA2134UAG4

Overview

The INA2134UAG4 is a dual-channel differential line receiver manufactured by Texas Instruments, housed in a 14-pin SOIC package. It operates with a supply voltage range of 8 V to 36 V and features a fixed gain of 1 V/V. The device supports single or dual power supplies, draws 2.4 mA of operating current, and delivers a slew rate of 14 V/us. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Provides balanced differential-to-single-ended conversion for audio signals
• Maintains high common-mode rejection ratio for noise suppression
• Operates on wide single or dual power supply voltages

Applications

• Professional audio equipment signal transmission
• Audio interface circuits requiring balanced input
• Line-level signal reception in recording systems

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the 14-pin SOIC package dimensions match the design footprint. Ensure the fixed unity gain configuration aligns with the system requirements, as external resistors are not used for gain adjustment in this variant.

Selection Notes

Select this component when a fixed unity gain differential receiver is required for professional audio applications. It is suitable for designs needing high common-mode rejection without external gain-setting components. Verify that the 14-pin SOIC package fits the PCB layout constraints and that the 8 V minimum supply voltage meets the system power architecture.

Part Context

This part belongs to the INA2134 family of audio differential line receivers from Texas Instruments. It is designed specifically for transmitting and receiving balanced audio signals over long distances while rejecting common-mode noise. The device integrates precision matched resistors internally to ensure accurate gain and high CMRR performance.

Replacement Considerations

The OPA2134 series serves as an operational amplifier alternative but requires external feedback networks for similar functionality. Verify pin compatibility and gain configuration differences before substitution.
