The AD5233 is a quad-channel nonvolatile memory,* digitally controlled potentiometer** 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 program-ming 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. The part is guaranteed to operate over the extended industrial temperature range of −40°C to +85°C.
Applications
* The terms nonvolatile memory and EEMEM are used interchangeably.
** The terms digital potentiometer and RDAC are used interchangeably.
