Differential Analog Input (Input) - Differential Audio Signal Inputs for channel 1 and channel 2.
25
2 Digital Power (Input) - Supply for digital logic. Connect to 5VGEN.
3
22
Gain (Input) - Gain select bits. GAIN0 is the least significant bit.
4 Digital Ground (Input) - Ground reference for the internal logic and digital I/O.
5 Reference (Output) - Internal reference voltage.
6
Sleep (Input) - When set to logic high, device enters low power mode. If not used, this pin should be
grounded.
7
Mute (Input) - When set to logic high, both amplifiers are muted and in Idle Mode. When low
(grounded), both amplifiers are fully operational. If not used, this pin should be grounded.
Status (Output) - A logic high output indicates over-current or under-voltage condition, thermal over-
8
load, that an output is shorted to ground or to another output, that the device is in low power mode (the
SLEEP pin is high), or that the device is in reset. A logic low state indicates that the CS3511 is ready to
output audio.
