ISL90841WIV1427Z-TK

Digital Potentiometers Overview

The ISL90841WIV1427Z-TK is a low noise, low power quad digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It integrates four independent potentiometers on a monolithic CMOS integrated circuit, utilizing resistor elements and CMOS switches for implementation. The device features an I2C serial interface for wiper position control via associated Wiper Registers. Key electrical specifications include a typical wiper resistance of 70Ω at 3.3V, standby current less than 5µA maximum, and operation within a power supply range of 2.7V to 5.5V. Total resistance options are 50kΩ or 10kΩ with 256 taps providing 0.4% resolution.

Digital Potentiometers Feature Summary

Digital Potentiometers Part Context

This component belongs to the ISL90841 family of XDCPs from Intersil/Renesas. The 'TK' suffix typically denotes a specific tape and reel packaging configuration for surface-mount assembly, distinct from bulk or tube packaging variants like the standard Z suffix.

Digital Potentiometers Replacement Considerations

Compatible substitutes within the same family include the ISL90841WIV1427Z. Designers should verify that the replacement part matches the required total resistance value (10kΩ or 50kΩ) and confirms the I2C address compatibility.
