The TAS5342 is a high-performance, integrated stereo digital amplifier power stage designed to drive a 4-ohm bridge-tied load (BTL) at up to 100W per channel with low harmonic distortion, low noise, and low idle current. It has a complete protection system to safeguard the device against a wide range of fault conditions. Supports multiple power output modes.
The TAS5342 is a high‑performance, integrated stereo digital amplifier power stage designed to deliver up to 100 W per channel into a 4‑Ω bridge‑tied load with low distortion and high efficiency. It includes a complete on‑chip protection system covering under‑voltage, over‑temperature, overload, short‑circuit, and PWM activity detection, and features a power‑on‑reset circuit to simplify system design.
The device is supplied in a thermally enhanced 44‑pin HTSSOP (DDV) package with an exposed PowerPAD™ thermal pad for efficient heat dissipation. Recommended operating conditions include PWM frame rates from 192 kHz to 432 kHz and supply voltages up to 13.2 V. Detailed pin assignments, thermal data, and absolute maximum ratings are provided for designers.
