• Built in I2C Bus for stand-by, mute, voltage gain control, self diagnosis: Output short detection, offset detection,

tweeter or speaker open detection (pin 22 and 25)

• Built-in various protection circuits (Note 1, Note 2)

Thermal shut down, over-voltage, out to GND, out to VCC, out to out short circuit

• Operating supply voltage: VCC (opr) = 9 to 18 V (RL = 4 Ω)

VCC (opr) = 9 to 16 V (RL = 2 Ω)
