Digital Potentiometers Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance and 'TK' denotes tape-and-reel packaging when sourcing. Confirm the manufacturer source is Intersil or its successor Renesas Electronics. Ensure the component matches the 8-MSOP footprint and 10 kΩ specification required by the design. Check datasheet revisions for any pinout or electrical parameter updates before finalizing procurement.

Digital Potentiometers Selection Notes

Select this component when a single-channel, non-volatile-free digital potentiometer with I²C control is required. The 10 kΩ value and 256 taps offer high resolution for fine adjustments. Consider the 8-MSOP package size constraints and the need for a serial bus line. Verify that the linear taper meets the application's transfer function requirements compared to logarithmic alternatives.

Digital Potentiometers Part Context

This part belongs to the ISL90810 family of single digitally controlled potentiometers. It is designed for applications requiring remote programmable resistance adjustment via a standard two-wire serial interface. The series is commonly used in industrial and consumer electronics where space-saving solutions for analog trimming are needed.

Digital Potentiometers Replacement Considerations

Cross-reference with ISL90810WAU8Z-TK for alternative package options if available. Verify compatibility with existing I²C addresses and logic levels. Ensure substitute parts maintain the same 10 kΩ resistance and 256-tap resolution.
