Pin No. Mnemonic Description

1

NC

Tie to Ground1 or Pin 16.

2

VCC

Positive Power Supply Voltage.

3

ENBL

Logic 1 enables the part, and Logic 0 disables the part.

4

VOUT

Open End of Internal 10 kΩ Resistor. Tie one end of external antialiasing filter capacitor (6.8 nF) to this pin, and tie

the other end to ground.1

5

CF2

Tie one end of the CFILTER (68 nF) that is in parallel with the internal gain resistor to this pin.

6

CF1

7

NC

Tie the other end of the CFILTER (68 nF) that is in parallel with the internal gain resistor to this pin.

Tie to Ground.1

8

NC

Tie to Ground.1

9

NC

Tie to Ground.1

10

GND

Ground1 or Negative Power Supply Voltage.

11

RSET

12

NC

Tie one end of Resistor RSET to this pin to set the excitation current and tie the other end of Resistor RSET to Pin 10.

Tie to Ground.1

13

IOUT

Excitation Current Output. Tie one end of CBRIDGE (0.1 μF) to this pin and tie the other end of CBRIDGE to ground.1

14

VINN

Negative Input Terminal.

15

VINP

Positive Input Terminal.

16

NC

Tie to Ground1 or Pin 1.

17/Pad NC

Pad should be floating and not tied to any potential.

1 During dual-supply operation, ground becomes the negative power supply voltage.
