PAM8610
10W STEREO CLASS-D AUDIO POWER AMPLIFIER WITH DC VOLUME CONTROL
Description
The PAM8610 is a 10W (per channel) stereo Class-D audio amplifier
with DC Volume Control which offers low THD+N (0.1%), low EMI,
and good PSRR thus high-quality sound reproduction. The 32 steps
DC volume control has a +32dB to -75dB range.
Pin Assignments
The PAM8610 runs off of a 7V to 15V supply at much higher
efficiency than competitors’ ICs.
The PAM8610 only requires very few external components,
significantly saving cost and board space.
The PAM8610 is available in a 40pin QFN 6mm*6mm package.

Function
Negative differential audio input for right channel.
Positive differential audio input for right channel.
5V Analog VDD
Analog reference for gain control section.
DC voltage that sets the gain of the amplifier.
Ground for gain control circuitry. Connect to AGND. If using a DAC to control the
volume, connect the DAC ground to this terminal.
Analog GND
Input for controlling volume ramp rate when cycling SD or during power-up. A
logic low on this pin places the amplifier in fade mode. A logic high on this pin
allows a quick transition to the desired volume setting.
Positive differential audio input for left channel.
Negative differential audio input for left channel.
Power ground for left channel H-bridge.
Power supply for left channel H-bridge, not connected to PVCCR or AVCC.
Class-D 1/2-H-bridge negative output for left channel.
Bootstrap I/O for left channel, negative high-side FET.
Bootstrap I/O for left channel, positive high-side FET.
Class-D 1/2-H-bridge positive output for left channel.
Internally generated voltage supply for left channel bootstrap capacitors.
I/O for charge/discharging currents onto capacitor for ramp generator triangle
wave biased at V2P5.
Current setting resistor for ramp generator. Nominally equal to 1/8*VCC.
Analog GND
A logic high on this pin disables the outputs and a logic low enables the outputs.
High-voltage analog power supply (7V to 15V)
2.5V Reference for analog cells, as well as reference for unused audio input
when using single-ended inputs.
Shutdown signal for IC (low = shutdown, high = operational). TTL logic levels with
compliance to VCC.
Internally generated voltage supply for right channel bootstrap capacitors.
Power ground for right channel H-bridge.
Power supply for right channel H-bridge, not connected to PVCCL or AVCC.
Class-D 1/2-H-bridge positive output for right channel.
Bootstrap I/O for right channel, positive high-side FET.
Bootstrap I/O for right channel, negative high-side FET.
Class-D 1/2-H-bridge negative output for right channel.
