3 Description
The TAS5352A device is a high-performance,
integrated stereo digital amplifier power stage
designed to drive a 4-Ω bridge-tied load (BTL) at up
to 125 W per channel with low harmonic distortion,
low integrated noise, and low idle current.
The TAS5352A 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, overcurrent protection, undervoltage
protection, overtemperature 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.
