ADN2850BCPZ25-RL7

Digital Potentiometers Overview

The ADN2850BCPZ25-RL7 is a dual-channel, non-volatile digital potentiometer manufactured by Analog Devices Inc. It features a total resistance of 250 kΩ with 1024 tap positions and an SPI control interface. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V or dual supplies up to ±2.75 V. Packaged in a 16-pin LFCSP, it includes non-volatile memory to retain wiper settings during power-off. Key electrical parameters include a resistance tolerance of ±8% and a temperature coefficient of ±35 ppm/°C, operating within a temperature range of -40°C to +85°C.

Digital Potentiometers Procurement Notes

Verify the specific suffix '-RL7' against official Analog Devices documentation to confirm reel packaging specifications. Ensure the part number matches the exact resistance value (250 kΩ) and package type (LFCSP-16). Cross-reference with manufacturer datasheets to validate pinout and electrical characteristics before procurement.

Digital Potentiometers Selection Notes

Select this component when non-volatile storage for resistance settings is required without external EEPROM. Verify that the 250 kΩ resistance value aligns with circuit impedance requirements. Confirm compatibility with the system's SPI clock speeds and voltage levels. Consider the ±8% tolerance for applications requiring precise resistance matching.

Digital Potentiometers Part Context

This part belongs to the ADN2850 family of non-volatile digital potentiometers. It shares architectural similarities with other models in the series but differs in resistance value and packaging options. The ADN2850 series is designed for applications needing reliable, digitally adjustable resistance with data retention capabilities.

Digital Potentiometers Replacement Considerations

Check for direct substitutes within the ADN2850 family with different resistance values or packages. Verify pin-to-pin compatibility if replacing existing components. Consult Analog Devices for updated alternatives if the specific '-RL7' variant is discontinued.
