ISL23711UIU10Z-T

Digital Potentiometers Overview

The ISL23711UIU10Z-T is a volatile digitally controlled potentiometer (XDCP) featuring an I²C serial interface. It provides 128 taps with a nominal resistance of 10kΩ, housed in a 10-lead MSOP package. The device operates on a VCC supply from 2.7V to 5.5V and supports dual supplies ranging from -2.7V to -5.5V for the negative rail. Key electrical characteristics include a typical total resistance temperature coefficient of ±50ppm/°C and a ratiometric temperature coefficient of ±4ppm/°C. Active current consumption is limited to 200µA maximum, while standby current remains below 500nA.

Digital Potentiometers Procurement Notes

Verify that the part number suffix includes '-T' to confirm tape and reel packaging, as indicated in the ordering information notes. Ensure the base model matches the required resistance value, as the 'U' suffix denotes the 50kΩ option while 'W' denotes 10kΩ. Confirm RoHS compliance and Pb-Free status if required by assembly specifications.

Digital Potentiometers Selection Notes

Select this component when a volatile digital potentiometer with I²C control is required. The 'U' variant offers 50kΩ resistance, whereas the 'W' variant provides 10kΩ. Note that the wiper position is volatile and resets to the center tap (64 decimal) upon power-up. Ensure the application voltage stays within the ±5.5V limits for both positive and negative rails.

Digital Potentiometers Part Context

This device belongs to the Intersil XDCP™ family of digitally controlled potentiometers. It integrates a resistor array, wiper switches, and an I²C control section into a single CMOS chip. The specific model ISL23711UIU10Z-T represents the 50kΩ version packaged in a 10-lead MSOP format.

Digital Potentiometers Replacement Considerations
