AD5259BRMZ50-R7

Digital Potentiometers Overview

The AD5259BRMZ50-R7 is a nonvolatile, I2C-compatible digital potentiometer featuring 256 adjustable positions. It provides a nominal end-to-end resistance of 50 kΩ with ±30% tolerance stored in EEPROM for 0.1% accuracy. The device operates on a single 2.7 V to 5.5 V supply and includes a separate VLOGIC pin for interface flexibility. Address pins AD0 and AD1 allow up to four devices on one bus. It utilizes an MSOP-10 package and supports software write protection.

Digital Potentiometers Procurement Notes

Verify the specific suffix R7 indicates tape and reel packaging when sourcing. Confirm the BRMZ designation corresponds to the MSOP-10 package variant. Ensure compatibility with the required 50 kΩ resistance value and I2C bus addressing configuration before integration.

Digital Potentiometers Selection Notes

Select this component for applications requiring precise electronic adjustment without mechanical wear. The 50 kΩ resistance value suits moderate impedance circuits. The nonvolatile feature eliminates the need for external storage for calibration data. Verify that the operating temperature range of −40°C to +125°C meets system requirements.

Digital Potentiometers Part Context

This part belongs to the AD5259 series of nonvolatile digital potentiometers. It serves as a solid-state replacement for mechanical potentiometers, offering enhanced resolution and reliability. The BRMZ50 variant specifically denotes the 50 kΩ resistor option in the compact MSOP-10 package.

Digital Potentiometers Replacement Considerations

Direct substitutes include other AD5259 variants with different resistance values or packages, such as AD5259BCPZ100-R7 for LFCSP packaging.
