INA2134UA/2K5E4

Overview

The INA2134UA/2K5E4 is a dual-channel differential line receiver from Texas Instruments, designed for high-performance audio applications. It features a fixed unity gain of 1 V/V and operates on a supply voltage range of 8 V to 36 V. The device draws a typical operating current of 2.4 mA and delivers a slew rate of 14 V/μs. It is housed in a 14-pin SOIC package and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrated precision laser-trimmed resistors ensure accurate unity gain and high common-mode rejection without external components.
• Dual independent channels provide isolation to minimize crosstalk and interaction between circuits.
• Wide output voltage swing and high drive capability support demanding load requirements.

Applications

• Audio differential line receivers
• Ground loop eliminators
• Summing amplifiers

Procurement Notes

Verify the suffix E4 indicates lead-free composition consistent with RoHS standards. Confirm the SOIC-14 package dimensions match the target PCB footprint. Ensure the operating environment stays within the specified -40°C to +85°C range. Check humidity sensitivity levels for proper storage and reflow profiles during assembly.

Selection Notes

Select this component when a dual-channel solution with fixed unity gain is required. It serves as a direct alternative to the single-channel INA134 when two isolated paths are needed. The wide supply voltage range accommodates various analog power rails. Consider the 14-pin package size relative to available board space.

Part Context

This part belongs to the INA2134 series of audio line receivers. It shares architectural similarities with the INA134 but offers two independent channels instead of one. The family is characterized by low distortion and high slew rates suitable for professional audio signal processing.

Replacement Considerations

The INA134UA/2K5 is a single-channel variant within the same family. Verify if the application requires only one channel or if the additional channel provides necessary isolation. Package differences may require schematic adjustments.
