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.
Supply voltage and temperature grade
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. The -40°C to 85°C rating means it can live in outdoor broadcast vans, stage racks, or factory-floor audio distribution panels where the ambient temperature swings beyond commercial limits.
Package and mounting
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. The supplier device package is also 14-SOIC, so no footprint mismatch between the generic and supplier-specific land pattern.
Lifecycle and compliance
The INA2134UA carries an Active lifecycle status and is ROHS3 compliant. No end-of-life notice or last-time-buy window is flagged.
