ISL95711WIU10Z

Digital Potentiometers Overview

The ISL95711WIU10Z is a digitally controlled potentiometer (XDCP) featuring an I2C serial interface and nonvolatile memory. It provides 128 wiper tap points with a total resistance of 10kΩ. The device operates on dual supplies, VCC from 2.7V to 5.5V and V- from -2.7V to -5.5V. Key specifications include a typical temperature coefficient of ±50ppm/°C for end-to-end resistance and a ratiometric temperature coefficient of ±4ppm/°C. It supports up to four devices per bus via hardware address selection and offers high reliability with 200,000 endurance cycles and 50-year data retention.

• High reliability: 200,000 write cycles and 50-year data retention

Digital Potentiometers Applications

• Industrial and automotive control systems
• Parameter and bias adjustments in electronic circuits
• Amplifier bias and control applications

Digital Potentiometers Procurement Notes

Verify the ordering suffix 'WIU10Z' corresponds to the 10kΩ resistance option and 10 Ld MSOP package. Confirm the '-T' suffix is required if tape and reel packaging is needed instead of tube. Ensure compatibility with RoHS compliance standards for Pb-free plus anneal products.

Digital Potentiometers Selection Notes

Select the ISL95711UIU10Z variant if a 50kΩ resistance value is required instead of the 10kΩ version. Consider the maximum wiper current limits when designing for rheostat mode. Verify that the I2C bus speed does not exceed 400kHz and that pull-up resistors are selected appropriately for the bus capacitance.

Digital Potentiometers Part Context

This component belongs to the Intersil ISL95711 series of Digitally Controlled Potentiometers. It is part of the XDCP family, which integrates resistor arrays, wiper switches, and nonvolatile memory into a single IC. The series typically includes variants with different resistance values and interface options, such as Up/Down interfaces.
