AD5290YRMZ10

Digital Potentiometers Overview

The AD5290YRMZ10 is a high-voltage, 8-bit digital potentiometer featuring 256 tap positions and a nominal resistance of 10 kΩ. It operates on single supplies from +4.5 V to +33 V or dual supplies from ±4.5 V to ±16.5 V. The device utilizes a 3-wire SPI-compatible serial interface for control. Key electrical specifications include a typical total harmonic distortion (THD) of 0.006%, a wiper resistance of 50 Ω, and a temperature coefficient of 35 ppm/°C. It is housed in a compact 10-MSOP package and supports operation across an extended automotive temperature range of −40°C to +125°C.

Digital Potentiometers Procurement Notes

Verify the specific resistance value suffix in the part number against the datasheet ordering guide, as the AD5290 series includes 10 kΩ, 50 kΩ, and 100 kΩ variants. Confirm that the YRMZ10 designation corresponds to the 10 kΩ version in the manufacturer's current documentation. Check for any recent revision changes to the data sheet that might affect pinout or electrical characteristics.

Digital Potentiometers Selection Notes

Select this component when high voltage tolerance up to 30 V is required in a small MSOP-10 package. Ensure the application can accommodate the ±30% resistor tolerance if absolute precision is critical. Consider the 35 ppm/°C temperature coefficient for thermal stability requirements. Verify that the 3-wire serial interface timing constraints align with the host microcontroller's clock speeds.

Digital Potentiometers Part Context

The AD5290 belongs to Analog Devices' iCMOS™ process technology family, designed for high-performance analog systems at higher voltage levels. It serves as a solid-state alternative to mechanical potentiometers, offering enhanced reliability and programmability. The YRMZ10 suffix indicates the 10 kΩ resistance variant within the broader AD5290 product line.

Digital Potentiometers Replacement Considerations

Direct replacements within the same family include the AD5290BRUZ (TSSOP-14 package) or other resistance variants like AD5290BRMZ50. When substituting, verify package dimensions and pin compatibility. Note that different suffixes may indicate different resistance values or packaging types rather than functional changes.
