AD5235BRUZ25 Datasheet PDF - ADI

The AD5235BRUZ25 is a Dual 1024-position Non-volatile Memory Digital Potentiometer offering guaranteed maximum low resistor tolerance error of ±8%. The device performs the same electronic adjustment function as a mechanical potentiometer with enhanced resolution, solid state reliability and superior low temperature coefficient performance. The versatile programming of the AD5235 via an SPI®-compatible serial interface allows 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 the scratchpad programming mode, a specific setting can be programmed directly to the RDAC2 register, which sets the resistance between Terminal W and Terminal A and Terminal W and Terminal B.
