d = 10 %
â 26 W/4 Ω @ VS = 14.4 V, f = 1 kHz,
d = 10 %
â Differential inputs (either single ended or
differential input signal are accepted)
â Minimum external component count:
â No bootstrap capacitors
â No Boucherot cells
â Internally fixed gain (30 dB)
â No SVR capacitor
â Standby function (CMOS compatible)
â Programmable turn-on/off delay
â No audible pop during mute and stand-by
operations
Protections
â Short circuit (to GND, to VS, across the load)
â Very inductive loads
