1 16 PWUP Apply a positive voltage (1.3 V ≤ VPWUP ≤ VPOS) to activate device. 2 1 RGP1 Gain Resistor Input 1. 3 2 INHI Balanced Differential Input. Biased to midsupply, typically ac-coupled. 4 3 INLO Balanced Differential Input. Biased to midsupply, typically ac-coupled. 5 4 RGP2 Gain Resistor Input 2. 6 9 COMM Device Common. Connect to low impedance ground. 7 10 OPLO Balanced Differential Output. Biased to VOCM, typically ac-coupled. 8 11 OPHI Balanced Differential Output. Biased to VOCM, typically ac-coupled. 9 12 VPOS Positive Supply Voltage. 3 V to 5.5 V. 10 13 VOCM Voltage applied to this pin sets the common-mode voltage at both the input and output. Typically decoupled to ground with a 0.1 μF capacitor. 5, 6, 7, 8, 14, 15 NC No connect. Do not connect to this pin. EPAD Exposed Pad. The exposed pad is internally connected to GND and must be soldered to a low impedance ground plane. Rev.
