AD5204 SOIC/TSSOP/PDIP Pin Configuration Table 3. AD5204 SOIC/TSSOP/PDIP Pin Function Descriptions Pin No. Name Description 1, 2, 12 NC Not Connected. 3 GND Ground. 4 CS Chip Select Input (Active Low). When CS returns high, data in the serial input register is decoded based on the address bits, and then it is loaded into the target RDAC latch. 5 PR Preset to Midscale (Active Low). This pin sets the RDAC registers to 0x80. 6 VDD Positive Power Supply. This pin is specified for operation at both 3 V and 5 V. It is the sum of |VDD| + |VSS| < 5.5 V. 7 SHDN Terminal A Open-Circuit Shutdown (Active Low Input). This pin controls VR 1 through VR 4. 8 SDI Serial Data Input. Data is input MSB first. 9 CLK Serial Clock Input. This pin is positive edge triggered. 10 SDO Serial Data Output. This pin is an open-drain transistor and requires a pull-up resistor. 11 VSS Negative Power Supply. This pin is specified for operation at both 0 V and −2.7 V. It is the sum of |VDD| + |VSS| < 5.5 V. 13 B3 Terminal B RDAC 3. 14 W3 Wiper RDAC 3. Address = 0102. 15 A3 Terminal A RDAC 3. 16 B1 Terminal B RDAC 1. 17 W1 Wiper RDAC 1.
