ANALOG DEVICES AD5292SRUZ-20-EP Non Volatile Digital Potentiometer, 20 kohm, Single, SPI, Linear, ± 1%, 2.7 V

AD5292SRUZ-20-EP is a single-channel, 1024-position digital potentiometer that combines industry-leading variable resistor performance with non-volatile memory (NVM) in a compact package. This device is capable of operating across a wide voltage range, supporting both dual supply operation at ±10.5V to ±16.5V and single-supply operation at +21V to +33V, while ensuring less than 1% end-to-end resistor tolerance error and offering 20-time programmable (20-TP) memory. The guaranteed industry-leading low resistor tolerance error feature simplifies open-loop applications as well as precision calibration and tolerance matching applications. It is used in applications such as mechanical potentiometer replacement, instrumentation: gain and offset adjustment, programmable voltage-to-current conversion, programmable filters, delays, and time constants, programmable power supply, low-resolution DAC replacement, and sensor calibration.
