X9261US24Z

Digital Potentiometers Overview

The X9261US24Z is a dual digital potentiometer manufactured by Intersil, now part of Renesas. It features two independent 50 kΩ wiper resistors with 256 tap positions for precise resistance adjustment. The device utilizes a 3-wire serial control interface (SPI compatible) for communication. It operates on a single supply voltage ranging from 2.7 V to 5.5 V and is housed in a 24-pin TSSOP package. The component supports non-volatile memory storage for wiper settings.

Digital Potentiometers Feature Summary

• Dual 50 kΩ digital potentiometers with 256 adjustable tap positions
• 3-wire serial control interface compatible with SPI protocols
• Single supply operation from 2.7 V to 5.5 V
• Non-volatile memory retains wiper position upon power cycle

Digital Potentiometers Applications

• Audio volume and tone control circuits
• Programmable gain amplifier biasing
• Voltage reference adjustment
• LCD contrast control

Digital Potentiometers Procurement Notes

Verify the manufacturer designation as Intersil or Renesas depending on the production era. Confirm the suffix 'Z' indicates RoHS compliance. Ensure the package type matches the required 24-pin TSSOP footprint. Check for specific tape-and-reel options if automated assembly is planned.

Digital Potentiometers Selection Notes

Select this component when dual independent variable resistors are required within a single package. The 50 kΩ resistance value suits moderate current applications. Verify that the 3-wire serial interface aligns with the host microcontroller's available pins. Consider the operating voltage range to ensure compatibility with the system logic levels.

Digital Potentiometers Part Context

This part belongs to the X9261 family of digital potentiometers. It shares architectural similarities with other models in the series but differs in pin count and channel configuration. The transition from Intersil to Renesas affects branding but not the core electrical specifications documented in original datasheets.

Digital Potentiometers Replacement Considerations

Cross-reference with X9261 variants having different suffixes for packaging changes. Verify functional equivalence with other dual digital potentiometers offering 256 taps and 3-wire interfaces. Ensure pinout compatibility before substituting.
