FUNCTION
Ground connection for circuitry, directly connected to thermal pad.
I Bit 0 of gain control
I Bit 1 of gain control
O Left channel + output in BTL mode
I Negative left input for fully differential inputs.
Power supply for output stages.
I Positive right input for fully differential inputs. AC ground for single-ended inputs.
O Left channel - output in BTL mode
I 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.
I Negative right input for fully differential inputs.
O Right channel + output in BTL mode
I Places entire IC in shutdown mode when held low
