INA2134UA/2K5

Overview

The INA2134UA/2K5 is a dual-channel differential line receiver from Texas Instruments, housed in a 14-pin SOIC package. It operates on a supply voltage range of 8 V to 36 V with a typical quiescent current of 2.4 mA. The device provides a fixed gain of 1 V/V (0 dB) and features a slew rate of 14 V/μs. It functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Dual independent circuits designed for minimal crosstalk and interaction between channels
• On-chip laser-trimmed precision resistors ensure accurate gain and high common-mode rejection
• High output drive capability supports demanding audio applications

Applications

• Audio differential line receivers
• Ground loop eliminators
• Summing amplifiers
• Instrumentation building blocks

Procurement Notes

Verify the specific suffix /2K5 indicates reel packaging configuration. Confirm RoHS compliance status through official documentation. Ensure the SOIC-14 package dimensions match PCB footprint requirements. Validate humidity sensitivity handling procedures during assembly.

Selection Notes

Select this component for applications requiring precise unity-gain differential signal conversion. The dual-channel architecture reduces board space compared to single-channel alternatives. Verify that the 8 V minimum supply voltage aligns with system power rails. Consider the 14-pin package availability for manufacturing constraints.

Part Context

This part belongs to the INA2134 series of audio line receivers. It serves as the dual-channel counterpart to the single-channel INA134. Both devices share similar internal architectures utilizing precision resistor networks for gain setting and common-mode rejection capabilities.

Replacement Considerations

INA134UA/2K5: Single-channel version; requires two units for dual-channel functionality.
