ISL22316UFRT10Z-TK

Digital Potentiometers Overview

The ISL22316UFRT10Z-TK is a single-channel digitally controlled potentiometer (DCP) from the Renesas ISL22316 series. It integrates non-volatile memory to retain wiper settings during power loss. The device features a linear resistance taper with 128 taps and offers a total resistance of 10 kΩ. It operates on a supply voltage range of 2.7 V to 5.5 V with a typical supply current of 5 µA. Communication is handled via an I²C serial interface, allowing direct control of the wiper position through volatile and non-volatile registers.

Digital Potentiometers Feature Summary

• Single channel DCP with 128 resistor taps and linear taper
• Non-volatile memory for wiper position retention
• I²C serial interface with up to eight devices per bus
• Supply voltage range: 2.7 V to 5.5 V

Digital Potentiometers Applications

• Control systems requiring parameter adjustments
• Signal processing circuits
• Industrial controls

Digital Potentiometers Procurement Notes

Verify the specific suffix 'TK' against official Renesas documentation to confirm packaging details, as standard listings often indicate tube packaging. Ensure the component matches the 10-TDFN-EP package dimensions and RoHS compliance status specified in the datasheet before procurement.

Digital Potentiometers Selection Notes

Select this component when a single-channel digital potentiometer with I²C control is required. The 10 kΩ resistance value and 128-tap resolution are suitable for precision adjustment tasks. Verify that the operating temperature range of -40°C to +125°C meets the environmental requirements of the target application.

Digital Potentiometers Part Context

This part belongs to the ISL22316 family of low-noise, low-power digital potentiometers. It is functionally similar to the ISL22316WFRT10Z but may differ in packaging or tape-and-reel configuration indicated by the suffix. The base model provides a robust solution for replacing mechanical potentiometers in space-constrained designs.

Digital Potentiometers Replacement Considerations

The ISL22416UFRT10Z is listed as a discontinued alternative; however, it uses an SPI interface rather than I²C, requiring software adaptation. Direct pin-to-pin replacements with identical interfaces should be verified against the latest Renesas product selection guide.
