ISL22424UFR16Z-TK

Digital Potentiometers Overview

The ISL22424UFR16Z-TK is a digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It features four independent circuits, each with 256 taps and a resistance value of 50k ohms. The device utilizes an SPI interface for communication and incorporates non-volatile memory to retain wiper settings upon power loss. It operates within a supply voltage range of ±2.25V to 5.5V and supports a linear taper configuration. The component is housed in a 16-lead QFN package and is rated for industrial temperature ranges from -40°C to +125°C.

Digital Potentiometers Feature Summary

• Four independent digital potentiometer circuits with 256 taps each
• Non-volatile memory retains wiper position after power cycle
• SPI serial interface for control and data transfer
• Industrial temperature range operation (-40°C to +125°C)

Digital Potentiometers Applications

• Expand output circuitry and voltage variation range circuits
• Robotic crane control circuits
• Thyristor pulse triggering circuits

Digital Potentiometers Procurement Notes

Verify the specific suffix 'TK' against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications. Confirm that the 16-QFN package dimensions match the design footprint requirements. Ensure compatibility with the system's SPI protocol timing and voltage levels before integration.

Digital Potentiometers Selection Notes

Select this component when four isolated digital pots are required in a compact form factor. The 50k ohm resistance and 256-tap resolution suit applications needing precise analog adjustment without mechanical wear. Verify that the ±2.25V to 5.5V supply range aligns with the target system's power rails.

Digital Potentiometers Part Context

This part belongs to the ISL22424 family of low-power, low-noise digitally controlled potentiometers. It is functionally related to other variants such as the ISL22424UFV14Z, which offers a different package option. The device represents Renesas's continuation of Intersil's XDCP technology line.
