Features

Most digital potentiometers are limited in the voltages that they can have at the end terminals to be within +5V and Ground. This makes operation with high voltages difficult. This design allows for higher voltages on the end terminals.

  • Single-channel, 256-/1024-position resolution
  • 20 kΩ, 50 kΩ, and 100 kΩ nominal resistance
  • Maximum ±1% nominal resistor tolerance error (resistor performance mode)
  • 20-times programmable wiper memory
  • Rheostat mode temperature coefficient: 35 ppm/°C
  • Voltage divider temperature coefficient: 5 ppm/°C
  • +9 V to +33 V single-supply operation
  • +9 V to -16.5 V dual-supply operation
  • See data sheet for additional features
