The AD5233 is a quad-channel nonvolatile memory,1 digitally controlled potentiometer2 with a 64-step resolution. The device 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.The EEMEM content can be restored dynamically or through external PR strobing. A WP function protects EEMEM contents. To simplify the programming, independent or simultaneous increment or decrement commands can be used to move the RDAC wiper up or down, one step at a time. For logarithmic ?6 dB step changes in wiper settings, the left or right bit shift command can be used to double or halve the RDAC wiper setting.The AD5233 is available in a thin 24-lead TSSOP package.
