TAS5342LA

illustrate

The TAS5342LA is a high performance, integrated stereo digital amplifier power stage designed to drive 4Ω bridge load (BTL) up to 100 watts per channel with low harmonic distortion, low noise integration and low standby current.

The TAS5342LA has a complete protection system integrated chip, and failure to guarantee conditions can damage the entire system-wide equipment. These protection features include short-circuit protection, overcurrent protection, under-voltage protection, over-temperature protection, and loss of pulse-width modulated signals (PWM activity detectors).

A power-on reset (POR) circuit is used to eliminate the sequencing of power supplies, which is required for most power stage designs.
