X9269US24-2.7

Digital Potentiometers Overview

The X9269US24-2.7 is a dual digital potentiometer manufactured by Intersil, now part of Renesas Electronics. It features two independent 50 kOhm resistive elements with 256 tap positions for precise resistance adjustment. The device utilizes a 2-wire serial control interface for data transmission and includes non-volatile memory to retain wiper settings during power-off states. It operates within a supply voltage range of 2.7 V to 5.5 V and is housed in a 24-pin SOIC package.

Digital Potentiometers Feature Summary

• Dual 50 kOhm digital potentiometers with 256 linear tap positions
• Non-volatile memory retains wiper position after power loss
• 2-wire serial control interface for simplified connectivity
• Operates on a single supply voltage from 2.7 V to 5.5 V

Digital Potentiometers Applications

• Programmable gain amplifiers
• Voltage reference trimming
• Audio volume control circuits
• Sensor bias adjustment

Digital Potentiometers Procurement Notes

Verify the manufacturer status as Intersil was acquired by Renesas Electronics. Confirm the specific suffix requirements for packaging and temperature grade against current Renesas documentation. Check component availability as legacy models may have limited stock or end-of-life status.

Digital Potentiometers Selection Notes

Select this component when dual independent digital pots are required in a compact SOIC-24 package. Ensure the 50 kOhm resistance value matches the circuit design. Verify that the 2-wire serial interface is compatible with the host microcontroller's available pins and protocol support.

Digital Potentiometers Part Context

This component belongs to the X9269 series of digital potentiometers. It shares architectural similarities with other members like the X9268 and X9269 variants, differing primarily in resistance values and package options. The series is designed for applications requiring adjustable resistance without mechanical moving parts.

Digital Potentiometers Replacement Considerations

Direct replacements include the X9269US24IZ-2.7T1 for industrial temperature ranges or the X9269TS24IZ-2.7T1 if a 100 kOhm variant is acceptable. Cross-reference with Renesas' current portfolio for updated pin-compatible alternatives.
