Description
The AD5272BRMZ-50 is a 50 kΩ digital potentiometer from Analog Devices, offering 1024 tap points (10-bit resolution) with ±1% resistor tolerance. It features a serial SPI interface for digital control and operates from 2.7V to 5.5V, making it suitable for low-power applications.
Key highlights:
- Non-volatile memory: Retains wiper settings during power-off.
- 50 kΩ end-to-end resistance with low temp coefficient (35 ppm/°C).
- ±20% tolerance programming for flexible adjustment.
- Small MSOP-10 package, ideal for space-constrained designs.
Common uses include gain adjustment, calibration, and programmable voltage dividers in industrial, automotive, and consumer electronics.
For detailed specs, refer to the datasheet.
