Pin Functions PIN TYPE(1) DESCRIPTION NO. NAME 1 MODSEL I Mode selection logic input (LOW = Ultra Low Idle Loss Mode, HIGH = BD Mode). TTL logic levels with compliance to AVCC. 2 SDZ I Shutdown logic input for audio amp (LOW = outputs Hi-Z, HIGH = outputs enabled). TTL logic levels with compliance to AVCC. 3 FAULTZ DO General fault reporting including Over-temp, DC Detect. Open drain. FAULTZ = High, normal operation FAULTZ = Low, fault condition 4 RINP I Positive audio input for right channel. Connect to GND for MONO mode. 5 RINN I Negative audio input for right channel. Connect to GND for MONO mode. 6 PLIMIT I Power limit level adjust. Connect a resistor divider from GVDD to GND to set power limit. Connect directly to GVDD for no power limit. 7 GVDD PO Internally generated gate voltage supply. Not to be used as a supply or connected to any component other than a 1 µF X7R ceramic decoupling capacitor and the PLIMIT and GAIN/SLV resistor dividers. 8 GAIN/SLV I Selects Gain and selects between Master and Slave mode depending on pin voltage divider. 9 GND G Ground 10 LINP I Positive audio input for left channel. Connect to GND for PBTL mode. 11 LINN I Negative audio input for left channel. Connect to GND for PBTL mode. 12 MUTE I Mute signal for fast disable/enable of outputs (HIGH = outputs Hi-Z, LOW = outputs enabled). TTL logic levels with compliance to AVCC. 13 AM2 I AM Avoidance Frequency Selection 14 AM1 I AM Avoidance Frequency Selection 15 AM0 I AM Avoidance Frequency Selection 16 SYNC DIO Clock input/output for synchronizing multiple class-D devices. Direction determined by GAIN/SLV terminal. 17 AVCC P Analog Supply |
