ISL22414WMU10Z-T7A

Digital Potentiometers Overview

The ISL22414WMU10Z-T7A is a single digitally controlled potentiometer (XDCP) from the XDCP™ family, manufactured by Renesas Electronics Corporation. It integrates a 10kΩ resistor network with 256 taps, control logic, and non-volatile memory on a monolithic CMOS IC. The device features a dual power supply capability, supporting VCC from 2.25V to 5.5V and V- from -2.25V to -5.5V, enabling bipolar operation. It communicates via an SPI serial interface and includes a volatile Wiper Register (WR), a non-volatile Initial Value Register (IVR), and 14 general-purpose non-volatile registers. The component is housed in a 10-lead MSOP package and operates within an extended industrial temperature range of -40°C to +125°C.

Digital Potentiometers Feature Summary

• Dual supply operation: VCC 2.25V–5.5V and V- -2.25V–-5.5V
• SPI serial interface with write/read capability and daisy-chain support
• Non-volatile EEPROM storage for wiper position and 14 general-purpose registers

Digital Potentiometers Applications

• Control and parameter adjustments in electronic systems
• Signal processing applications requiring variable resistance
• Bipolar range DCP terminal applications using dual supplies

Digital Potentiometers Procurement Notes

Verify that the specific ordering suffix corresponds to the military temperature range (-55°C to +125°C) and tape-and-reel packaging format. Confirm RoHS compliance status as per the manufacturer's current specifications. Check for any recommended replacement notices, as this part may be subject to obsolescence management protocols.

Digital Potentiometers Selection Notes

Select this component when a single-channel digital potentiometer with non-volatile memory retention is required. Ensure the application supports the SPI protocol and dual-supply voltage requirements if bipolar operation is necessary. Verify that the 10kΩ resistance value and 256-tap resolution meet the circuit's precision needs.

Digital Potentiometers Part Context

This part belongs to the ISL22414 series of low-noise, low-power digitally controlled potentiometers. The 'W' suffix indicates a 10kΩ resistance option, while 'MU' denotes the 10-lead MSOP package with military temperature rating. The '-T7A' suffix specifies the reel packaging configuration. The series shares architectural similarities with other XDCP™ devices but offers specific pinout and performance characteristics defined by its datasheet.

Digital Potentiometers Replacement Considerations

The datasheet lists ISL22414TFU10Z-TK as the recommended replacement for obsolete variants in the series. Verify compatibility regarding package dimensions, electrical parameters, and software register maps before substitution.
