Table 4. Pin Function Descriptions Pin No. Mnemonic Description
1 VIN Negative Side of Balanced Differential Inputs for Amplifier 1. This pin is biased to the VCC voltage (VVCC)/2, and is typically ac-coupled. 2 VIP Positive Side of Balanced Differential Inputs for Amplifier 1. This pin is biased to VVCC/2, and is typically ac-coupled. 3, 11 GND Ground. Ground reference for the entire chip. These pins must be soldered to a low impedance ground plane. 4 VIP2 Positive Side of Balanced Differential Inputs for Amplifier 2. This pin is biased to the VCC2 voltage (VVCC2)/2 and is typically ac-coupled. 5 VIN2 Negative Side of Balanced Differential Inputs for Amplifier 2. This pin is biased to VVCC2/2 and is typically ac-coupled. 6 PDB2 Power-Down Control (Active Low) for Amplifier 2. This pin is internally pulled up to approximately 2.8 V. A logic high on this pin (2.1 V < PDB2 voltage (VPDB2) < 3.3 V) enables the device. 7 VCOM2 Common-Mode Voltage Input for Amplifier 2. A voltage applied to this pin sets the common-mode voltage of the inputs and outputs of the amplifier. If left open, the VCOM2 voltage (VVCOM2) = VCC2/2. Decouple this pin to ground with a 0.1 µF capacitor. 8 VCC2 Positive Supply for Amplifier 2. 9 VON2 Negative Side of Balanced Differential Outputs for Amplifier 2. This pin is biased to VVCOM2 and is typical y ac-coupled. 10 VOP2 Positive Side of Balanced Differential Outputs for Amplifier 2. This pin is biased to VVCOM2 and is typically ac-coupled. 12 VOP Positive Side of Balanced Differential Outputs for Amplifier 1. This pin is biased to VVCOM and is typically ac-coupled. 13 VON Negative Side of Balanced Differential Outputs for Amplifier 1. This pin is biased to VVCOM and is typical y ac-coupled. 14 VCC Positive Supply for the Amplifier 1. 15 VCOM Common-Mode Voltage Input for Amplifier 1. A voltage applied to this pin sets the common-mode voltage of the inputs and outputs of the amplifier. If left open, VVCOM = VVCC/2. Decouple this pin to ground with a 0.1 µF capacitor. 16 PDB Power-Down Control (Active Low) for Amplifier 1. This pin is internally pulled up to approximately 2.8 V. A logic high on this pin (2.1 V < PDB voltage (VPDB) < 3.3 V) enables the device. EPAD Exposed Pad. The exposed pad is internal y connected to GND and must be soldered to a low impedance ground plane. Rev.
