Table 4. Pin Function Descriptions
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 VLOGIC
2.7 V to 5.5 V Logic Supply Voltage. The logic supply voltage should always be less than or equal to VDD. In addition, logic
levels must be limited to the logic supply voltage regardless of VDD.
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 VDD 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 No Connection in SPI Mode. Digital Output O2 in I2C Mode. Can be used to drive external logic.
18 VSS
Negative Power Supply. Specified for operation from 0 V to –5 V.
19 W4
Wiper Terminal W4 (ADDR = 11).
20 A4
Resistor Terminal A4.
21 B4
Resistor Terminal B4.
22 W2
Wiper Terminal W2 (ADDR = 01).
23 A2
Resistor Terminal A2.
24 B2
Resistor Terminal B2.
