Analog Devices AD5272BRMZ-100 Digital Potentiometer

The AD5272BRMZ-100 from Analog Devices Inc. is a high-performance digital potentiometer that offers a precise and reliable solution for applications requiring adjustable resistance settings. This device provides a single-channel, 1024-position digital potentiometer with a fixed end-to-end resistance of 100 kΩ. It is an ideal choice for applications such as calibration, adjustable gain control, and signal conditioning in a wide array of industries including automotive, medical, and industrial automation.

Featuring a compact 10-lead MSOP (Mini Small Outline Package), the AD5272BRMZ-100 is designed for space-constrained applications. It operates from a 2.7V to 5.5V supply, making it versatile for both single-supply and dual-supply operations. The digital potentiometer integrates a precision, non-volatile memory (EEPROM) that ensures resistance settings remain intact even after power-off conditions, providing an added layer of reliability for critical applications.

Communication with the AD5272BRMZ-100 is implemented via a standard I²C-compatible serial interface, allowing easy integration into existing digital systems. This interface facilitates the programming of resistance values without the need for complex signal routing, which simplifies PCB design and reduces system complexity.

The device boasts an impressive temperature coefficient of 35 ppm/°C, ensuring stable performance over a wide temperature range. Additionally, the AD5272BRMZ-100 features a robust power-on recall feature where the last saved resistance setting is automatically reinstated upon power-up, thus simplifying the initialization process.

Key features of the AD5272BRMZ-100 include:

• 100 kΩ end-to-end resistance
• 1024-position resolution
