FUNCTION
Shutdown logic input for audio amp (Low=outputs disabled, High=output
enabled). TTL logic levels with compliance to AVDD.
Protection flag output (open drain). Connecting FLAG and SD can be set to
auto-recovery. Otherwise need to reset by cyding AVDD
Positive audio input for left channel. Biased at VCLAMP/2.
Negative audio input for left channel. Biased at VCLAMP/2.
Gain select least significant bit. TTL logic levels with compliance to AVDD.
Gain select least significant bit. TTL logic levels with compliance to AVDD.
Analog supply.
Analog signal ground. Connect to the thermal pad.
Regulated voltage, Nominal voltage is 5V.
Power limit level adjust. Connect a resistor divider from VCLAMP to GND to
set power limit. Connect directly to VCLAMP for no power limit.
Negative audio input for right channel. Biased at VCLAMP/2.
Positive audio input for right channel. Biased at VCLAMP/2.
Not connected.
Parallel BTL mode switch.
Power supply for right channel H-bridge. Right channel and left channel power
supply inputs are connected internally.
Bootstrap I/O for right channel, positive high-side FET.
Class-D H-bridge positive output for right channel.
Power ground for the H-bridges.
Class-D H-bridge negative output for right channel.
Bootstrap I/O for right channel, negative high-side FET.
Bootstrap I/O for left channel, negative high-side FET.
Class-D H-bridge negative output for left channel.
Class-D H-bridge positive output for left channel.
Bootstrap I/O for left channel, positive high-side FET.
Power supply for left channel H-bridge. Right channel and left channel power
supply inputs are connected internally.
