Table 4. Pin Function Descriptions Pin No. Mnemonic Description
1 VIN1 Negative Side of Balanced Differential Inputs for Amplifier 1. This pin is biased to VVCC1/2, and is typically ac- coupled. 2 VIP1 Positive Side of Balanced Differential Inputs for Amplifier 1. This pin is biased to VVCC1/2, and is typically ac- coupled. 3, 4, 7, 12, 15, NC No Functional Connection. Connect these pins to ground. 16, 19, 24 5 VIP2 Positive Side of Balanced Differential Inputs for Amplifier 2. This pin is biased to VVCC2/2, and is typically ac- coupled. 6 VIN2 Negative Side of Balanced Differential Inputs for Amplifier 2. This pin is biased to VVCC2/2, and is typically ac- coupled. 8 PM2 Power Mode Control for Amplifier 2. This pin is internally pulled down to GND through a 30 kΩ resistor. A logic low on this pin sets the device to high performance mode, and a logic high (2.1 V < VPM2 < 3.3 V) sets the device to low power mode. 9 ENBL2 Enable for Amplifier 2. This pin is internally pulled up to about 2.8 V. A logic high on this pin (2.1 V < VENBL2 < 3.3 V) enables the device. 10 VCOM2 Common-Mode Voltage. A voltage applied to this pin sets the common-mode voltage of the inputs and outputs of Amplifier 2. If left open, VVCOM2 = VCC2/2. Decouple this pin to ground with a 0.1 μF capacitor. 11 VCC2 Positive Supply for Amplifier 2. 13 VON2 Negative Side of Balanced Differential Outputs for Amplifier 2. This pin is biased to VVCOM2, and is typically ac- coupled. 14 VOP2 Positive Side of Balanced Differential Outputs for Amplifier 2. This pin is biased to VVCOM2, and is typically ac- coupled. 17 VOP1 Positive Side of Balanced Differential Outputs for Amplifier 1. This pin is biased to VVCOM1, and is typically ac- coupled. 18 VON1 Negative Side of Balanced Differential Outputs for Amplifier 1. This pin is biased to VVCOM1, and is typically ac- coupled. 20 VCC1 Positive Supply for Amplifier 1. 21 VCOM1 Common-Mode Voltage. A voltage applied to this pin sets the common-mode voltage of the inputs and outputs of Amplifier 1. If left open, VVCOM1 = VCC1/2. Decouple this pin ground with a 0.1 μF capacitor. 22 ENBL1 Enable for Amplifier 1. This pin is internally pulled up to about 2.8 V. A logic high on this pin (2.1 V < VENBL1 < 3.45 V) enables the device. 23 PM1 Power Mode Control for Amplifier 1. This pin is internally pulled down to GND through a 30 kΩ resistor. A logic low on this pin sets the device to high performance mode, and a logic high (2.1 V < VPM1 < 3.45 V) sets the device to low power mode. EP GND Exposed Pad. The exposed pad is internally connected to GND and must be soldered to a low impedance ground plane.
