The TAS5261 is a high-performance, integrated mono digital amplifier power stage designed to drive 4- speakers with low harmonic distortion. This system requires only a simple, passive demodulation filter to deliver high-quality, high-efficiency audio amplification.

The TAS5261 has complete protection circuitry integrated on chip, safeguarding the device and speakers against fault conditions that could damage the system. These protection features are short-circuit protection, overcurrent protection, undervoltage protection, and a loss of pulse-width modulation (PWM) input signal (PWM Activity Detector).

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