AD5231BRUZ100

AD5231 is a non-volatile memory, digitally controlled potentiometer with 1024-step resolution. The device performs the same electronic adjustment function as a mechanical potentiometer with enhanced resolution, solid state reliability, and remote controllability. The device 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, ±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 table, or system identification information. It is widely used in application such as mechanical potentiometer replacement, instrumentation: gain, offset adjustment, programmable voltage to current conversion, programmable filters, delays, time constants, programmable power supply, low resolution DAC replacement, sensor calibration etc.
