ISL22424UFV14Z-TK

Digital Potentiometers Overview

The ISL22424UFV14Z-TK is a digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It integrates two independent digital potentiometers, each offering 256 tap positions for precise resistance adjustment. The device utilizes an SPI serial interface for control and features non-volatile memory to retain wiper settings during power-off conditions. Designed for industrial applications, it operates within a temperature range of -40°C to 125°C and supports supply voltages from ±2.25V to 5.5V.

Digital Potentiometers Feature Summary

• Dual-channel configuration with 256 taps per channel
• SPI serial interface for digital control
• Non-volatile memory retains wiper position after power loss
• Industrial temperature range: -40°C to 125°C

Digital Potentiometers Applications

• Adjustable gain control in instrumentation amplifiers
• Programmable voltage reference circuits
• Digital trimming of analog signal paths
• Calibration systems requiring persistent resistance settings

Digital Potentiometers Procurement Notes

Verify the specific suffix 'TK' against official Renesas documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with existing SPI bus protocols and voltage levels before integration. Cross-reference the full part number with current manufacturer status to confirm availability and lifecycle stage.

Digital Potentiometers Selection Notes

Select this component when dual-channel digital adjustment with non-volatile retention is required. The 256-tap resolution provides fine granularity for calibration tasks. Verify that the 14-TSSOP package fits the PCB layout constraints and that the operating voltage range aligns with the system's power supply rails.

Digital Potentiometers Part Context

This part belongs to the ISL22424 family of XDCP™ devices. It shares core functionality with variants like the ISL22424UFV14Z but may differ in packaging or shipping format. The 'U' typically denotes an industrial temperature grade, while 'FV14' indicates the 14-pin TSSOP package type.

Digital Potentiometers Replacement Considerations

Direct substitutes include other ISL22424 variants with compatible pinouts and electrical characteristics. Verify that alternative parts maintain the same 256-tap resolution and non-volatile memory features. Check for any differences in serial interface timing or voltage tolerances.
