d = 10 %
– 26 W/4 Ω @ VS = 14.4 V, f = 1 kHz,
d = 10 %
■ Differential inputs (either single ended or
differential input signal are accepted)
■ Minimum external component count:

– No Boucherot cells
– Internally fixed gain (30 dB)
– No SVR capacitor
■ Standby function (CMOS compatible)
■ Programmable turn-on/off delay
■ No audible pop during mute and stand-by
operations
Protections
■ Short circuit (to GND, to VS, across the load)
■ Very inductive loads
■ Chip over temperature
■ Load dump
■ Open GND
