Custom Digital Potentiometerspot

Compact digitally controlled potentiometers for general purpose applications such as audio volume control, power control, and bias voltage control. Modular design enables fast custom configuration.

Features

  • Very low area achieved through the use of custom decode logic. Efficient for multiple use in complex SoC's for improved yield, trimming, characterization, and testability.
  • Rail to rail operation.
  • 100 to 1M Ohm input resistance range.
  • 16 - 2048 potentiometer steps.
  • Linear, log, and anti-log, or custom transfer function options.
  • 100nS step switching time.
  • Static or registered data option.
