Description
The AD5251BRUZ100-RL7 is a digital potentiometer from the AD5251 series produced by Analog Devices Inc. This product belongs to the category of digital potentiometers and is used for electronic adjustment functions, like mechanical potentiometers, trimmers, and variable resistors. The AD5251BRUZ100-RL7 is a dual-channel device and has 64 positions resolution. It features non-volatile memory that stores wiper setting with write protection, and EEMEM settings, which are power-on refreshed in 300 µs and have rewrite time of 540 µs. The device stores resistance tolerance in non-volatile memory and has extra EEMEM for storing user-defined information. It is I2C-compatible with a serial interface, has a bandwidth of 4 MHz, and operates at temperatures ranging from -40°C to +105°C.

- Programmable power supply
- Sensor calibrations
Comparison
Advantages- Digital potentiometer allows for accurate electronic adjustment functions compared to mechanical potentiometers and trimmers.
- The non-volatile memory feature stores wiper setting with write protection and EEMEM settings, which are power-on refreshed and have a rewrite time of 540 µs typ.
- I2C-compatible serial interface enables easy communication with other devices.
- Synchronous or asynchronous dual-channel update allows for flexible operation.
Disadvantages- The device has a limited range of resolution options with only 64 positions (AD5251).
- The operational temperature range is limited to -40°C to +105°C, which may not be suitable for some environments.
