Terminal Functions
Analog ground for digital/analog cells in core
High-voltage analog power supply (8.5 V to 14 V)
5-V Regulated output capable of 100-mA output
5-V Reference output—provided for connection to adjacent VREF terminal.
Bootstrap I/O for left channel, negative high-side FET
Bootstrap I/O for left channel, positive high-side FET
Bootstrap I/O for right channel, negative high-side FET
Bootstrap I/O for right channel, positive high-side FET
I/O for charge/discharging currents onto capacitor for ramp generator triangle wave biased at V2P5
Negative differential audio input for left channel
Positive differential audio input for left channel
Class-D 1/2-H-bridge negative output for left channel
Class-D 1/2-H-bridge positive output for left channel
Input for MODE control. A logic high on this pin places the amplifier in the variable output mode and the Class-D
outputs are disabled. A logic low on this pin places the amplifier in the Class-D mode and Class-D stereo outputs
are enabled. Variable outputs (VAROUTL and VAROUTR) are still enabled in Class-D mode to be used as
line-level outputs for external amplifiers.
Output for control of the variable output amplifiers. When the MODE pin (34) is a logic high, the MODE_OUT
pin is driven low. When the MODE pin (34) is a logic low, the MODE_OUT pin is driven high. This pin is
intended for MUTE control of an external headphone amplifier. Leave unconnected when not used for
headphone amplifier control.
Power ground for left channel H-bridge
Power ground for right channel H-bridge
Power supply for left channel H-bridge (tied to pins 22 and 23 internally), not connected to PVCCR or AVC
Power supply for left channel H-bridge (tied to pins 14 and 15 internally), not connected to PVCCR or AVC
Power supply for right channel H-bridge (tied to pins 46 and 47 internally), not connected to PVCCL or AVC
Power supply for right channel H-bridge (tied to pins 38 and 39 internally), not connected to PVCCL or AVC
Ground for gain control circuitry. Connect to AGND. If using a DAC to control the volume, connect the DAC
ground to this terminal.
