4 / 16 page  IS31AP2110 Integrated Silicon Solution, Inc. – www.issi.com 4 Rev. A, 09/01/2014 PIN DESCRIPTION No. Pin Description 1 SDB Shutdown signal for IC (Low = disabled, output Hi-Z; High = operational). Voltage compliance to 26V. 2 FAULTB Open drain output used to display short circuit or dc detect fault. Voltage compliant to 26V. Short circuit faults can be set to auto- recovery by connecting FAULTB pin to SDB pin. Otherwise, both short circuit faults and dc detect faults must be reset by cycling VCC. 3 INL+ Positive audio input for left channel. Biased at 1.65V. 4 INL- Negative audio input for left channel. Biased at 1.65V. 5 GAIN0 Gain select least significant bit. Voltage compliance to 26V. 6 GAIN1 Gain select most significant bit. Voltage compliance to 26V. 7,13,17, 21,22,26 NC Not connected. 8 AGND Analog signal ground. Connect to the thermal pad. 9 AVDD 3.3V regulated output. 10 PLIM Power limit level adjustment. Connect a resistor divider from AVDD to GND to set power limit. Give VPLIMIT <1.55V to set power limit level. Connect to both of AVDD (>1.55V) and GND are all without power limit feature. 11 INR- Negative audio input for right channel. Biased at 1.65V. 12 INR+ Positive audio input for right channel. Biased at 1.65V. 14 PBTL Parallel BTL mode switch, high for parallel BTL output. Voltage compliance to 26V. 15, 16 VCCR High-voltage power supply for right-channel. Right channel and left channel power supply inputs are connect internal. 18 OUTR+ Class-D H-bridge positive output for right channel. 19 PGND Power ground for the H-bridges. 20 OUTR- Class-D H-bridge negative output for right channel. 23 OUTL- Class-D H-bridge negative output for left channel. 24 PGND Power ground for the H-bridges. 25 OUTL+ Class-D H-bridge positive output for left channel. 27, 28 VCCL High-voltage power supply for left-channel. Right channel and left channel power supply inputs are connect internal. Thermal Pad Connect to GND. |
