1, 4 INP1, INP2 Positive Inputs. 2, 3 INN1, INN2 Negative Inputs. 5, 16 VREF2, VREF1 Voltage Reference Inputs. Sets the output dc bias voltage. Internally biased to +VS/2 when left floating. See the Applications Information section. 6, 15 GND2, GND1 Power Supply Ground Pins. 7, 14 +VS2, +VS1 Positive Power Supply Pins. These pins must be connected together, to the same voltage. Bypass these pins with a 0.1 µF capacitor to ground. 8, 13 ENA2, ENA1 Enable Pins. Connect to +VS or float for normal operation and to ground for device disable. 9, 12 VOUT2, VOUT1 Amplifier Outputs. 10, 11 STB2, STB1 Short-to-Battery Indicator Output Pins. A logic low indicates an overvoltage condition (short-to-battery), whereas a logic high indicates normal operation. An open-drain configuration requires an external pull-up resistor. EPAD Exposed Pad. The exposed pad is located on the bottom side of the package. The pad is not connected electrically, but should be soldered to a metalized area on the PCB to minimize thermal resistance. Rev.
