ISL95810UIU8

Digital Potentiometers Overview

The ISL95810UIU8 is a single-channel digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It features a total resistance of 50 kΩ with linear taper and 256 resistor taps, providing 0.4% resolution. The device operates on a power supply ranging from 2.7V to 5.5V and utilizes an I²C serial interface for communication. Key electrical parameters include a typical wiper resistance of 70Ω at 3.3V, a standby current of 5µA maximum, and a temperature coefficient of ±45ppm/°C. The component integrates non-volatile memory to store the wiper position.

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as specific manufacturing batches may vary. Check for end-of-life notices or obsolescence warnings prior to procurement planning. Ensure proper handling procedures are followed due to surface-mount packaging requirements.

Digital Potentiometers Selection Notes

Select this model when a 50kΩ resistance value is required. Verify that the 8-lead MSOP package fits the PCB layout constraints. Ensure the host system supports the I²C protocol and can provide the necessary voltage levels between 2.7V and 5.5V. Consider the 256-tap resolution against application precision needs.

Digital Potentiometers Part Context

This component belongs to the XDCP™ series of digitally controlled potentiometers. It is part of a family that includes variants with different resistance values and packaging options, such as the 10kΩ version (ISL95810WIU8). The device represents a CMOS integrated circuit solution replacing mechanical potentiometers in digital control environments.

Digital Potentiometers Replacement Considerations

Direct replacement options include the ISL95810UIU8Z variant, which offers Pb-free plus anneal construction while maintaining identical electrical specifications and pinout compatibility.
