Texas Instruments DRV134UASell Excess Inventory

The DRV134UA from Texas Instruments is a professional-grade differential audio line driver that converts single-ended audio inputs into balanced outputs with exceptional accuracy and low distortion. Designed for studio, broadcasting, and industrial systems, this precision amplifier delivers outstanding signal integrity across long cable runs. Available now at OEMSTOCK with fast global delivery and verified quality.

General Description

The DRV134 family consists of high-performance differential output amplifiers optimized for professional and Hi-Fi audio systems. Each device integrates a precision operational amplifier with laser-trimmed on-chip resistors to ensure accurate gain, low distortion, and superior common-mode rejection ratio (CMRR).

The DRV134UA operates from a ±4.5 V to ±18 V supply and features a high slew rate of 15 V/µs, allowing it to drive long audio cables or capacitive loads without signal degradation. When paired with the INA134 or INA137 differential line receivers, it forms a complete, noise-free balanced transmission system ideal for professional and industrial environments.

Packaged in a compact SOIC-8 (SO-8) form factor, the DRV134UA supports operating temperatures from −40°C to +85°C, ensuring robust and stable performance in demanding conditions.

FAQs

What is the DRV134UA used for?

The DRV134UA is used to convert single-ended analog signals into balanced outputs for professional audio, broadcast, or industrial communication systems.

What is the difference between DRV134 and DRV135?

The DRV134 provides two balanced outputs (dual channel) in a 16-pin package, while the DRV135 is a single-channel version in an 8-pin SOIC package.

Can the DRV134UA replace the SSM2142?

Yes. It is a direct drop-in, improved replacement for the SSM2142 with better distortion characteristics, higher slew rate, and extended supply voltage range.
