X9410WV24-2.7

Digital Potentiometers Overview

The X9410WV24-2.7 is a dual digitally controlled potentiometer (XDCP) manufactured by Intersil, now part of Renesas Electronics. It integrates two independent 10 kΩ resistor arrays, each providing 64 tap positions for precise resistance adjustment. The device utilizes a non-volatile memory architecture to retain wiper settings upon power loss. Control is achieved via a standard SPI serial interface, allowing direct read/write access to wiper positions and storage of multiple preset values. It operates on a single supply voltage ranging from 2.7 V to 5.5 V.

Digital Potentiometers Feature Summary

• Dual channel configuration with two independent 10 kΩ potentiometers
• Non-volatile memory retains wiper position data without power
• SPI serial control interface for register-oriented operations
• 64 discrete tap positions per potentiometer for linear resolution

Digital Potentiometers Applications

• Audio volume and tone control circuits
• Programmable gain amplifier biasing
• Voltage reference trimming
• Sensor calibration offset adjustment

Digital Potentiometers Procurement Notes

Verify the specific suffix '2.7' against official datasheets to confirm the minimum operating voltage rating and package type. Check current availability status as older Intersil components may be discontinued or subject to last-time-buy notices. Ensure compatibility with existing PCB footprints for the TSSOP-24 package if applicable.

Digital Potentiometers Selection Notes

Select this component when dual-channel digital adjustment is required within a low-voltage system. Confirm that the 10 kΩ resistance value and 64-step resolution meet the circuit's precision requirements. Verify that the host microcontroller supports the necessary SPI clock speeds and protocol timing for reliable communication with the device registers.

Digital Potentiometers Part Context

This part belongs to the X9410 family of solid-state potentiometers. It serves as an electronic alternative to mechanical pots, offering higher reliability and immunity to vibration. The 'WV' designation typically indicates a wide temperature range or specific packaging variant, while 'IZ' often denotes lead-free and RoHS compliance in Intersil nomenclature.

Digital Potentiometers Replacement Considerations

Direct substitutes include the ISL23033 or ISL8100 series from Renesas/Intersil. Verify pinout compatibility and interface protocol before substitution. Alternative manufacturers like Microchip offer similar SPI-controlled digital potentiometers, but parameter matching for voltage range and resistance tolerance is essential.
