1. NC = NO CONNECT. THESE PINS SHOULD BE

CONNECTED TO GROUND.

2. THE EXPOSED PAD IS INTERNALLY CONNECTED TO

GND AND MUST BE SOLDERED TO A LOW IMPEDANCE

GROUND PLANE.

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,

16, 19, 24

NC

No Functional Connection. Connect these pins to ground.

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.
