Pin Descriptions
Pin Number Pin Name Function
1 RINN 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.
6 REF GND
Ground for gain control circuitry. Connect to AGND. If using a DAC to control the
volume, connect the DAC ground to this terminal.
7 AGND1 Analog GND
8 FADE
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.
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 LO UTP Class-D 1/2-H-bridge positive output for left channel.
21 VCLAMPL Internally generated voltage supply for left channel bootstrap capacitors.
22 CO SC
I/O for charge/discharging currents onto capacitor for ramp generator triangle
wave biased at V2P5.
23 RO SC 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)
27 V2P5
2.5V Reference for analog cells, as well as reference for unused audio input
when using single-ended inputs.
29 SD
Shutdown signal for IC (low = shutdown, high = operational). TTL logic levels with
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 ROUTN Class-D 1/2-H-bridge negative output for right channel.
