Product Introduction

Overview

The DRV135UA/2K5G4, produced by Texas Instruments, is a high-performance audio balanced line driver designed for demanding audio applications. This device is part of the DRV13x series, which includes the DRV134 and DRV135 models. The DRV135 is particularly noted for its compact SO-8 surface-mount package, making it ideal for space-constrained designs. It is characterized by its low differential-mode output impedance and high common-mode output impedance, ensuring excellent signal integrity and minimal distortion.

The DRV135 is optimized for use in balanced-pair audio systems, offering low total harmonic distortion plus noise (THD+N), a high slew rate, and a wide output voltage swing. These features make it suitable for a variety of applications, including professional audio equipment, telecommunications systems, and industrial instrumentation.
