(Sum of |VDD| + |VSS| £ 15 V) 5 SHDN Active low input. Terminal A open-circuit. Shutdown controls. Variable Resistors of RDAC. 6 CLK Serial Clock Input, positive edge triggered. 7 SDI Serial Data Input 8 CS Chip Select Input, Active Low. When CS returns high, data will be loaded into the RDAC register. 9 PR Active low preset to mid-scale; sets RDAC registers to 80H. 10 GND Ground 11 VSS Negative Power Supply, specified for operation from 0 V to –5 V. 12 VL Logic Supply Voltage, needs to be same voltage as the digital logic controlling the AD5260. 13 NC No Connect (Users should not connect anything other than dummy pad on this pin) 14 SDO Serial Data Output, Open Drain transistor requires pull-up resistor.
