1 VIP2 Balanced Differential Input. Biased to VCOM, typically ac-coupled. Input for AV = 12 dB gain, strapped to VIP1 for Av = 15.5 dB. 2 VIP1 Balanced Differential Input. Biased to VCOM, typically ac-coupled. Input for AV = 6 dB gain, strapped to VIP2 for Av = 15.5 dB. 3 VIN1 Balanced Differential Input. Biased to VCOM, typically ac-coupled. Input for AV = 6 dB gain, strapped to VIN2 for Av = 15.5 dB. 4 VIN2 Balanced Differential Input. Biased to VCOM, typically ac-coupled. Input for AV = 12 dB gain, strapped to VIN1 for Av = 15.5 dB. 5, 6, 7, 8 VCC Positive Supply. 9 VCOM Common-Mode Voltage. A voltage applied to this pin sets the common-mode voltage of the input and output. Typically decoupled to ground with a 0.1 µF capacitor. With no reference applied, input and output common mode floats to midsupply (VCC/2). 10 VON Balanced Differential Output. Biased to VCOM, typically ac-coupled. 11 VOP Balanced Differential Output. Biased to VCOM, typically ac-coupled. 12 ENBL Enable. Apply positive voltage (1.0 V < ENBL < VCC) to activate device. 13, 14, 15, 16 GND Ground. Connect to low impedance ground. EP Exposed Paddle. Connect to a low impedance thermal and electrical ground plane. Rev.
