BRIEF DESCRIPTION
INC Increment (INC).The INC input is negative-edge triggered.Toggling INC will move the wiper and either increment or decrement the counter in the direction indicated by the logic level on the U/D input.U/D Up/Down (U/D).The U/D input controls the direction of the wiper movem
Features
- Solid-state potentiometer.
- Up/Down interface.
- 32 wiper tap points - Wiper position stored in nonvolatile memory and recalled on power-up.
- 31 resistive elements - Temperature compensated - Maximum resistance tolerance of ±25% - Terminal voltage, 0 to VCC.
- Low power CMOS - VCC = 2.7V to 5.5V - Active current, 200µA typ. - Standby current, 2µA max.
- High reliability - Endurance 200,000 data changes per bit - Register data retention, 100 years.
