Table 5. ADA4830-1 P in Function Descriptions Pin No. Mnemonic Description
1 VREF Voltage Reference Input. Sets the output dc bias voltage. Internally biased to +VS/2 when left floating. See the Applications Information section. 2 INP Positive Input. 3 INN Negative Input. 4 GND Power Supply Ground Pin. 5 STB Short-to-Battery Indicator Output Pin. A logic low indicates an overvoltage condition (short-to-battery), whereas a logic high indicates normal operation. An open-drain configuration requires external pull-up resistor. 6 VOUT Amplifier Output. 7 ENA Enable Pin. Connect to +VS or float for normal operation. Connect to ground for device disable. 8 +VS Positive Power Supply Pin. Bypass this pin with a 0.1 µF capacitor to ground. 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 printed circuit board (PCB) to minimize thermal resistance. Rev.
