Product Overview

The AD5231BRUZ10 is a 1024-position Non-volatile Memory Digital Potentiometer that performs the same electronic adjustment function as a mechanical potentiometer with enhanced resolution, solid state reliability and remote controllability. It has versatile programming that uses a standard 3-wire serial interface for 16 modes of operation and adjustment, including scratchpad programming, memory storing and restoring, increment/decrement, ±6dB/step log taper adjustment, wiper setting readback and extra EEMEM for user-defined information, such as memory data for other components, look-up table or system identification information. In scratchpad programming mode, a specific setting can be programmed directly to the RDAC register that sets the resistance between Terminals W-A and Terminals W-B. This setting can be stored into the EEMEM and is transferred automatically to the RDAC register during system power-on.
  • Non-volatile memory maintains wiper setting
  • Power-on refresh with EEMEM setting
  • 140µs typical EEMEM restore time
  • Full monotonic operation
  • Permanent memory write protection
  • Wiper setting readback
  • Predefined linear increment/decrement instructions
  • Predefined ±6dB/step log taper increment/decrement instructions
  • SPI® compatible serial interface
