FUNCTION
Ground connection for circuitry, directly connected to thermal pad.
Bit 0 of gain control
Bit 1 of gain control
Left channel + output in BTL mode
Negative left input for fully differential inputs.
Power supply for output stages.
Positive right input for fully differential inputs. AC ground for single-ended inputs.
Left channel - output in BTL mode
Positive left input for fully differential inputs. AC ground for single-ended inputs.
Tap to voltage divider for internal mid-supply bias generator.
NC
O
Right channel - output in BTL mode
Analog VDD input supply. This terminal needs to be isolated from PVDD to achieve
highest performance.
Negative right input for fully differential inputs.
Right channel + output in BTL mode
Places entire IC in shutdown mode when held low
