Pin Configuration 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 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 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. |
