  – 4 x 50 W/4  max.
  – 4 x 30 W/4  @ 14.4 V, 1 kHz, 10 %
  – 4 x 80 W/2  max.
  – 4 x 55 W/2  @ 14.4 V, 1 kHz, 10 %
■ MOSFET output power stage
■ Excellent 2  driving capability
■ Hi-fi class distortion
■ Low output noise
■ Standby function
■ Mute function
■ Automute at min. supply voltage detection
■ Low external component count:
  – Internally fixed gain (26 dB)
  – No external compensation
  – No bootstrap capacitors
■ On board 0.35 A high side driver
■ Protections:
  – Output short circuit to GND, to Vs, across the load
  – Very inductive loads
  – Overrating chip temper.
