Description
A Terminal.
Wiper Terminal.
B Terminal.
Positive Power Supply. Specified for operation at both 5 V or 15 V (sum of |V
Active Low Input. Terminal A, open-circuit. Shutdown controls variable resistor.
Serial Clock Input, Positive Edge Triggered.
Serial Data Input.
Chip Select Input, Active Low. When CS returns high, data is loaded into the RDAC register.
Active Low Preset to Midscale. Sets RDAC registers to 0x80.
Ground.
Negative Power Supply. Specified for operation from 0 V to −5 V.
Logic Supply Voltage. Needs to be the same voltage as the digital logic controlling the AD5260.
No Connect. Users should not connect anything other than a dummy pad on this pin.
Serial Data Output. Open-drain transistor requires a pull-up resistor.
