Vic

Input common mode voltage(1)

I Voo I ≤ 40mV max with all differential gains except 24dB. For 24dB gain, input decoupling caps are

mandatory.

GND+0.5V to VCC-0.9V

VSTBY

Standby voltage input (2)

Device ON

Device in STANDBY(3)

Without any signal on VSTBY, the device is in standby (internal 300kΩ +/-20% pull-down resistor).

Minimum current consumption is obtained when VSTBY = GND.

VIH

GO, G1 - high level input voltage(4)

Between G0, G1pins and GND, there is an internal 300k

Ω (+/-20%) pull-down resistor. When pins are

floating, the gain is 6 dB. In full standby (left and right channels OFF), these resistors are disconnected

(HiZ input).
