100-W Stereo Digital Amplifier Power Stage - TAS5342

TAS5342 (NRND)

100-W Stereo Digital Amplifier Power Stage


Not Recommended for New Designs (NRND)

Replaced By TAS5342A– The device has the SAME FUNCTIONALITY and PINOUT as the compared device but is NOT an exact equivalent.

TI does not recommend using this part in a new design. This product continues to be in production to support existing customers.


The TAS5342 is a high-performance, integrated stereo digital amplifier power stage designed to drive a 4- bridge-tied load (BTL) at up to 100 W per channel with low harmonic distortion, low integrated noise, and low idle current.

The TAS5342 has a complete protection system integrated on-chip, safeguarding the device against a wide range of fault conditions that could damage the system. These protection features are short-circuit protection, over-current protection, under voltage protection, over temperature protection, and a loss of PWM signal (PWM activity detector).

A power-on-reset (POR) circuit is used to eliminate power-supply sequencing that is required for most power-stage designs.
