NAME

FUNCTION

1

HA

Resistor A High Terminal. The voltage at HA can be higher or lower than the voltage at LA. Current

can flow into or out of HA.

2

WA

Resistor A Wiper Terminal

3

LA

Resistor A Low Terminal. The voltage at LA can be higher or lower than the voltage at HA. Current

can flow into or out of LA.

4

HB

Resistor B High Terminal. The voltage at HB can be higher or lower than the voltage at LB. Current

can flow into or out of HB.

5

WB

Resistor B Wiper Terminal

6

LB

Resistor B Low Terminal. The voltage at LB can be higher or lower than the voltage at HB. Current

can flow into or out of LB.

7

I.C.

Internally Connected. Connect to GND.

8

GND

Ground

9

A2

Address Input 2. Connect to VDD or GND.

10

A1

Address Input 1. Connect to VDD or GND.

11

A0

Address Input 0. Connect to VDD or GND.

12

SDA

I2C-Compatible Serial-Data Input/Output. A pullup resistor is required.

13
