Left-Channel Negative Input (Stereo Mode Only)
Left-Channel Positive Input (Stereo Mode Only)
Mono/Stereo Mode Input. Drive logic high for mono mode. Drive logic low for stereo mode.
Internal Regulator Output Voltage (6V). Bypass with a 0.01µF capacitor to GND.
Analog Ground
Soft-Start. Connect a 0.47µF capacitor to GND to utilize soft-start power-up sequence.
Analog Power Supply. Bypass to GND with a 0.1µF capacitor as close to pin as possible.
Right-Channel Negative Input. In mono mode, INR- is the negative input.
Right-Channel Positive Input. In mono mode, INR+ is the positive input.
Gain Select input 1
