Pin No. Mnemonic Description

1

W

Wiper Terminal W. GND ≤ VW ≤ VDD.

2

VDD

Positive Power Supply. Specified for operation from 2.7 V to 5.5 V. For OTP programming, VDD needs to be within

the 4.75 V and 5.25 V range and capable of driving 100 mA.

3

GND

Common Ground.

4

SCL

Serial Clock Input. Requires a pull-up resistor. If it is driven direct from a logic controller without the pull-up

resistor, ensure that the VIH minimum is 0.7 V × VDD.

5

SDA

6

AD0

Serial Data Input/Output. Requires a pull-up resistor. If it is driven direct from a logic controller without a pull-up

resistor, ensure that the VIH minimum is 0.7 V × VDD.

I2C Device Address Bit. Allows a maximum of two AD5171s to be addressed.

7

B

Resistor Terminal B. GND ≤ VB ≤ VDD.

8

A

Resistor Terminal A. GND ≤ VA ≤ VDD.
