Applications
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.
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.
n Flat monitor /LCD TVS
n Multi-media speaker System
n DVD players, game machines
n Boom Box
n Music instruments

Function
Negative differential audio input for right channel
2 RINP Positive differential audio input for right channel
3 AVDD 5V Analog VDD
4 VREF Analog reference for gain control section
5 VOLUME DC voltage that sets the gain of the amplifier
Ground for gain control circuitry. Connect to AGND. If using a DAC to control the
6 REFGND
volume, connect the DAC ground to this terminal.
7 AGND1 Analog GND
Input for controlling volume ramp rate when cycling SD or during power-up. A
8 FADE 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.
9 LINP Positive differential audio input for left channel
10 LINN Negative differential audio input for left channel
11,20
PGNDL Power ground for left channel H-bridge
12,19
PVCCL Power supply for left channel H-bridge, not connected to PVCCR or AVCC.
13,14
LOUTN Class-D 1/2-H-bridge negative output for left channel
15 BSLN Bootstrap I/O for left channel, negative high-side FET
16 BSLP Bootstrap I/O for left channel, positive high-side FET
17,18
LOUTP Class-D 1/2-H-bridge positive output for left channel
21 VCLAMPL Internally generated voltage supply for left channel bootstrap capacitors.
I/O for charge/discharging currents onto capacitor for ramp generator triangle
22 COSC
wave biased at V2P5
23 ROSC Current setting resistor for ramp generator. Nominally equal to 1/8*VCC
24,28
AGND Analog GND
25 MUTE A logic high on this pin disables the outputs and a logic low enables the outputs.
26 AVCC High-voltage analog power supply (7V to 15V)
2.5V Reference for analog cells, as well as reference for unused audio input
27 V2P5
when using single-ended inputs.
Shutdown signal for IC (low= shutdown, high =operational). TTL logic levels with
29 SD
compliance to VCC.
30 VCLAMPR Internally generated voltage supply for right channel bootstrap capacitors.
31,40
PGNDR Power ground for right channel H-bridge
32,39
PVCCR Power supply for right channel H-bridge, not connected to PVCCL or AVCC.
33,34
ROUTP Class-D 1/2-H-bridge positive output for right channel
35 BSRP Bootstrap I/O for right channel, positive high-side FET
36 BSRN Bootstrap I/O for right channel, negative high-side FET
37,38
