Serial Data Output. Open-drain transistor requires a pull-up resistor.
Serial Data Input.
Ground.
Description
A Terminal RDAC 1.
Wiper RDAC 1, Address A0 = 0.
B Terminal RDAC 1.
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 1 through Resistor R2.
Serial Clock Input, Positive Edge Triggered.
Chip Select Input, Active Low. When CS returns high, data in the serial input register is decoded, based on the
Address Bit A0, and loaded into the target RDAC register.
Active Low Preset to Midscale. Sets RDAC registers to 0x80.
Negative Power Supply. Specified for operation at either 0 V or −5 V (sum of |V
Logic Supply Voltage. Needs to be same voltage as the digital logic controlling the AD5262.
B Terminal RDAC 2.
Wiper RDAC 2, Address A0 = 1.
A Terminal RDAC 2.
