AD5272BRMZ-50 Description

Short technical summary and product information.

The AD5272BRMZ-50 is a single-channel digital rheostat from Analog Devices offering 1024 tap positions with a nominal resistance of 50 kOhms. It features a maximum ±1% resistor tolerance error and a low temperature coefficient of 5 ppm/°C, ensuring stable performance over temperature. The device supports both single-supply operation from 2.7V to 5.5V and dual-supply operation from ±2.5V to ±2.75V, making it suitable for AC or bipolar applications.

 

The rheostat uses an I2C-compatible interface for digital control and includes non-volatile memory (50-TP) that retains the wiper setting at power-on. The wiper setting can be read back via the interface. The device is configured as a rheostat (two-terminal variable resistor) with linear taper.

 

Housed in a compact 10-lead MSOP package (3mm x 4.9mm x 1.1mm) with surface mount termination, the AD5272BRMZ-50 is suitable for space-constrained designs. It operates over the industrial temperature range of -40°C to +125°C. Typical applications include mechanical rheostat replacement, variable gain control in op-amp circuits, instrumentation gain and offset adjustment, programmable filters, and sensor calibration.
