Pin
Name
Description
1
B1
Resistor Terminal B1.
2
A1
Resistor Terminal A1 (ADDR = 00).
3
W1
Wiper Terminal W1.
4
B3
Resistor Terminal B3.
5
A3
Resistor Terminal A3.
6
W3
Wiper Terminal W3 (ADDR = 10).
7
VDD
Positive Power Supply, specified for +5 V to +15 V operation.
8
GND
Ground.
9
DIS
Digital Interface Select (SPI/I2C Select). SPI when DIS = 0, I2C when DIS = 1
10
V
LOGIC
2.7 V to 5.5 V Logic Supply Voltage. The logic supply voltage should always be less than or equal to V
DD. In addition, logic
levels must be limited to the logic supply voltage regardless of V
DD.
11
SDI/SDA
SDI = 3-Wire Serial Data Input. SDA = 2-Wire Serial Data Input/Output.
12
CLK/SCL
Serial Clock Input.
13
CS/AD0
Chip Select in SPI Mode. Device Address Bit 0 in I2C Mode.
14
RES/AD1
RESET in SPI Mode. Device Address Bit 1 in I2C Mode.
15
SHDN
Shutdown. Shorts wiper to Terminal B, opens Terminal A. Tie to +5 V supply if not used. Do not tie to V
DD if VDD > 5 V.
16
SDO/O1
Serial Data Output in SPI Mode. Open-drain transistor requires pull-up resistor.
Digital Output O1 in I2C Mode. Can be used to drive external logic.
17
NC/O2
