4 / 17 page Pin Number Name Function 1 RINN Negative differential audio input for right channel 2 RINP Positive differential audio input for right channel 3AVDD 5V Analog VDD 4 VREF Analog reference for gain control section 5 VOLUME DC voltage that sets the gain of the amplifier 6REFGND 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 LOUTP Class-D 1/2-H-bridge positive output for left channel 21 VCLAMPL Internally generated voltage supply for left channel bootstrap capacitors. 22 COSC I/O for charge/discharging currents onto capacitor for ramp generator triangle 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) 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 Pin Descriptions 4 , Power Analog Microelectronics Inc 08/2008 Rev 1.2 PAM8610 10W Stereo Class-D Audio Power Amplifier with DC Volume Control www.poweranalog.com |
