Analog ground
Tap to voltage divider for internal midsupply bias generator used for analog reference.
A capacitor connected to this terminal sets the oscillation frequency in conjunction with ROSC. For proper
operation, connect a 220 pF capacitor from COSC to ground.
Bit 0 of gain control (TTL logic level)
Bit 1 of gain control (TTL logic level)
Left channel negative differential audio input
Left channel positive differential audio input
Left channel negative audio output
Left channel positive audio output
Power ground for left channel H-bridge
Power ground for right channel H-bridge
Power supply for left channel H-bridge
Power supply for right channel H-bridge
Right channel negative differential audio input
Right channel positive differential audio input
A resistor connected to this terminal sets the oscillation frequency in conjunction with COSC. For proper
operation, connect a 120 kΩ resistor from ROSC to ground.
Right channel negative audio output
Right channel positive output
Places the amplifier in shutdown mode if a TTL logic low is placed on this terminal; normal operation if a TTL
logic high is placed on this terminal.
