Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | EN | input | Enable control pin: the part is enabled when pulled low, and an internal 40k pull-up turns the part off if the pin is unconnected. |
| 2 | GND | power_in | Ground reference for the enable pin and the bias control voltage pin, which must be connected externally to ground. |
| 3 | IN R | input | Red channel input with a nominal impedance of 200kΩ when the input bias circuit is inactive (pin 16 open). |
| 4 | GND R | power_in | Ground of the red channel amplifier, not internally connected to other ground pins, and must be connected externally to ground. |
| 5 | IN G | input | Green channel input with a nominal impedance of 200kΩ when the input bias circuit is inactive (pin 16 open). |
| 6 | GND G | power_in | Ground of the green channel amplifier, not internally connected to other ground pins, and must be connected externally to ground. |
| 7 | IN B | input | Blue channel input with a nominal impedance of 200kΩ when the input bias circuit is inactive (pin 16 open). |
| 8 | GND B | power_in | Ground of the blue channel amplifier, not internally connected to other ground pins, and must be connected externally to ground. |
| 9 | V+ B | power_in | Positive supply of the blue channel amplifier, not internally connected to other supply pins, and must be externally connected to the supply bus with proper bypassing. |
| 10 | OUT B | output | Blue channel output. |
| 11 | V+ G | power_in | Positive supply of the green channel amplifier, not internally connected to other supply pins, and must be externally connected to the supply bus with proper bypassing. |
| 12 | OUT G | output | Green channel output. |
| 13 | V+ R | power_in | Positive supply of the red channel amplifier, not internally connected to other supply pins, and must be externally connected to the supply bus with proper bypassing. |
| 14 | OUT R | output | Red channel output. |
| 15 | V+ | power_in | Positive supply voltage of the control circuitry, not internally connected to other supply pins, and must be externally connected to the supply bus with proper bypassing. |
| 16 | BCV | passive | Bias control voltage: a resistor between pin 16 and pin 2 (GND) generates a DC input bias voltage at the three amplifier inputs for AC coupling. |
