功能描述：
▪ Multipower BCD technology with DMOS MOSFET output power stage
▪ Hi-Fi class low distortion
▪ Low output noise
▪ High immunity to RF noise injection
▪ Standby function
▪ Mute function
▪ Auto-mute at min. supply voltage detection
▪ Low external component count
▪ No external compensation
▪ No bootstrap capacitors
▪ Internally fixed gain (26dB)
▪ Capable to operate down to 6V (e.g. “start-stop")
▪ High output power capability:
– 4 x 45W/4Ω Max.
– 4 x 25W/4Ω @ 14.4V, 1kHz, 10%
▪ Protections:
– Output short circuit to GND, to Vs, across the load
– Very inductive loads
– Overrating chip temperature with soft thermal limiter
– Load dump
– Fortuitous open GND
