ISL22323TFR16Z-TK

Digital Potentiometers Overview

The ISL22323TFR16Z-TK is a dual digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It integrates two independent 10kΩ resistive networks with 256 taps, controlled via an I2C serial interface. The device features non-volatile memory to retain wiper positions during power loss and operates within a supply voltage range of ±2.25V to 5.5V. Packaged in a 16-lead TSSOP format, it offers linear taper characteristics and typical wiper resistance of 70Ω. Key specifications include a temperature coefficient of ±85ppm/°C and an operating temperature range from -40°C to 125°C.

Digital Potentiometers Feature Summary

• Dual 10kΩ potentiometers with 256 taps each
• I2C serial interface with optional address pins
• Non-volatile storage for wiper position retention
• Shutdown mode with maximum 5µA current

Digital Potentiometers Applications

• Industrial control parameter adjustments
• Signal processing circuit calibration
• Consumer electronics volume or gain control

Digital Potentiometers Procurement Notes

Verify component status as the base model ISL22323WFV14Z is listed as obsolete. Confirm availability of the tape-and-reel variant ISL22323WFV14Z-TK through authorized distributors. Ensure RoHS3 compliance and check for any product change notices affecting packaging or labeling prior to procurement.

Digital Potentiometers Selection Notes

Select this component for designs requiring precise digital adjustment of analog parameters without mechanical potentiometers. Verify that the I2C bus speed and address configuration meet system requirements. Consider the 14-TSSOP package dimensions if space is constrained, noting the specific pinout for VCC, GND, SDA, and SCL connections.

Digital Potentiometers Part Context

This part belongs to the XDCP™ series of digitally controlled potentiometers from Renesas. It shares functional similarities with models like the ISL22326 but differs in tap count and package options. The series is designed for low-noise, low-power applications requiring reliable non-volatile memory storage for settings.

Digital Potentiometers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate cross-reference candidates based on identical I2C interface, 256-tap resolution, and 10kΩ resistance values.
