DESCRIPTION
No connect pin. Can be shorted to PVCC or shorted to GND or left open. TTL logic levels with compliance to AVCC. Shutdown logic input for audio amp (LOW, outputs Hi-Z; HIGH, outputs enabled). General fault reporting including OverTemp, Over-Current, DC Detect. SD/FAULT = High, normal operation, SD/FAULT = Low, and fault condition. Device will automatically recover once the OT/OC/DC Fault has been removed. Positive audio input for left channel. Biased at 2.5V. Connect to GND for PBTL mode. Negative audio input for left channel. Biased at 2.5V. Connect to GND for PBTL mode. Gain select least significant bit. TTL logic levels with compliance to AVDD. Low = 20dB gain, High = 26dB gain, Floating = 26dB gain. Mode select least significant bit. TTL logic levels with compliance to AVDD. Low = BD Mode/UV Threshold = 7.5V, High = Low-Idle-Current 1SPW Mode/UV Threshold = 3.4V, Floating = Low-Idle- Current 1SPW Mode/UV threshold = 3.4V Analog supply Analog signal ground FET gate drive supply.
