AD5233BRUZ10 Datasheet PDF - ADI

●The AD5233BRUZ10 is a quad-channel non-volatile Digital Potentiometer performs the same electronic adjustment function as a mechanical potentiometer with enhanced resolution, solid-state reliability and remote controllability. The AD5233 has versatile programming using a serial peripheral interface (SPI) for 16 modes of operation and adjustment, including scratchpad programming, memory storing and restoring, increment/decrement, ±6 dB/step log taper adjustment, wiper setting readback and extra EEMEM for user-defined information such as memory data for other components, look-up tables or system identification information. In the scratchpad programming mode, a specific setting can be programmed directly to the RDAC register, which sets the resistance between Terminal W to Terminal A and Terminal W to Terminal B. This setting can be stored into the EEMEM and is transferred automatically to the RDAC register during system power-on.
