Description

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.

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.

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.

VIN2

Negative Side of Balanced Differential Inputs for Amplifier 2. This pin is biased to VVCC2/2 and is typically ac-coupled.

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.

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.

VCC2

Positive Supply for Amplifier 2.

VON2

Negative Side of Balanced Differential Outputs for Amplifier 2. This pin is biased to VVCOM2 and is typically ac-coupled.

VOP2

Positive Side of Balanced Differential Outputs for Amplifier 2. This pin is biased to VVCOM2 and is typically ac-coupled.

VOP

Positive Side of Balanced Differential Outputs for Amplifier 1. This pin is biased to VVCOM and is typically ac-coupled.

VON

Negative Side of Balanced Differential Outputs for Amplifier 1. This pin is biased to VVCOM and is typically ac-coupled.

VCC

Positive Supply for the Amplifier 1.

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.

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 internally connected to GND and must be soldered to a low impedance ground plane.
