TAS5352A

illustrate

The TAS5352A is a high-performance, integrated stereo digital amplifier power stage designed to drive up to 4Ω bridged load (BTL) of 125 watts per channel with low harmonic distortion, low noise integration, and low standby current.

The TAS5352A has a chip for complete protection system integration, and failure of the safeguard condition can destroy the entire system-wide device. These protections include short-circuit protection, overcurrent protection, undervoltage protection, over-temperature protection, and loss of pulse-width modulated signals (PWM's activity detector).

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