DESCRIPTION
24-PIN
(PWP)
NAME
Shutdown signal for IC (low = disabled, high = operational). TTL logic levels with compliance to
AVCC.
Audio input for right channel.
Audio input for left channel.
Gain select least significant bit. TTL logic levels with compliance to AVCC.
Gain select most significant bit. TTL logic levels with compliance to AVCC.
Mute signal for quick disable/enable of outputs (high = outputs switch at 50% duty cycle, low =
outputs enabled). TTL logic levels with compliance to AVCC.
Bootstrap I/O for left channel.
Power supply for left channel H-bridge, not internally connected to PVCCR or AVCC.
Class-D 1/2-H-bridge positive output for left channel.
Power ground for left channel H-bridge.
Internally generated voltage supply for bootstrap capacitors.
Bootstrap I/O for right channel.
Class-D 1/2-H-bridge negative output for right channel.
Power ground for right channel H-bridge.
Power supply for right channel H-bridge, not connected to PVCCL or AVCC.
Analog ground for digital/analog cells in core.
Analog Ground for analog cells in core.
Reference for pre-amplifier inputs. Nominally equal to AVCC/8. Also controls start-up time via
external capacitor sizing.
High-voltage analog power supply. Not internally connected to PVCCR or PVCCL
Connect to ground. Thermal Pad should be soldered down on all applications to properly
secure device to printed wiring board.
