Shutdown signal for IC (LOW = disabled, HIGH = operational). TTL logic levels SHUTDOWN 61 I with compliance to AVCC. (Active low) RINN 5 I Negative audio input for right channel. Biased at VREG/2. RINP 6 I Positive audio input for right channel. Biased at VREG/2. LINN 9 I Negative audio input for left channel. Biased at VREG/2. LINP 8 I Positive audio input for left channel. Biased at VREG/2. GAIN0 10 I Gain select least significant bit. TTL logic levels with compliance to VREG. GAIN1 11 I Gain select most significant bit. TTL logic levels with compliance to VREG. Mute signal for quick disable/enable of outputs (HIGH = outputs high-Z, LOW = MUTE 62 I outputs enabled). TTL logic levels with compliance to AVCC. (Active high) TTL compatible output. HIGH = short-circuit fault. LOW = no fault. Only reports FAULT 63 O short-circuit faults. Thermal faults are not reported on this terminal. BSLP 26 I/O Bootstrap I/O for left channel, positive high-side FET. Power supply for left channel H-bridge, not internally connected to PVCCR or PVCCL 35, 36 AVCC. LOUTP 27, 28 O Class-D 1/2-H-bridge positive output for left channel. PGNDL 37, 38 Power ground for left channel H-bridge. LOUTN 29, 30 O Class-D 1/2-H-bridge negative output for left channel. BSLN 31 I/O Bootstrap I/O for left channel, negative high-side FET. VCLAMPL 40 Internally generated voltage supply for left channel bootstrap capacitor. VCLAMPR 41 Internally generated voltage supply for right channel bootstrap capacitor. BSRN 50 I/O Bootstrap I/O for right channel, negative high-side FET. ROUTN 51, 52 O Class-D 1/2-H-bridge negative output for right channel. PGNDR 43, 44 Power ground for right channel H-bridge. 5 Submit Documentation Feedback |
