Product details

Audio Differential Line Receiver in 14-SOIC

The Burr-Brown INA2134UA is an audio differential line receiver in a 14-SOIC package. It accepts a wide supply range of 8V to 36V (or ±4V to ±18V) and operates over the industrial temperature range of -40°C to 85°C. This part is designed to extract balanced audio signals from a twisted-pair line, rejecting common-mode noise picked up along the cable run. Typical applications include professional audio mixing consoles, studio monitors, and balanced line receivers in broadcast or installed-sound equipment.

The supply range covers both single-supply (8V to 36V) and split-supply (±4V to ±18V) configurations. That flexibility lets the INA2134UA drop into existing ±15V audio rails or a single 24V industrial supply without a regulator change.

Housed in a 14-SOIC (0.154" body width, 3.90 mm), the INA2134UA is a surface-mount part that reflows alongside standard passive components. The narrow SOIC footprint keeps board area tight for multi-channel audio cards.

Frequently asked questions

What is the INA2134UA used for?

The INA2134UA is an audio differential line receiver. It recovers balanced audio signals from twisted-pair cables while rejecting common-mode noise, making it a standard building block in professional audio gear, studio consoles, and broadcast equipment.

What is the closest pin-compatible alternative to the INA2134UA?

The INA2134UA is a specific audio differential line receiver from Burr-Brown. Pin-compatible alternatives within the same function family would include other Burr-Brown or TI differential line receivers in the 14-SOIC footprint, but the evidence does not list an exact second-source order code. For a drop-in substitute, verify the pinout against the datasheet.
