Digital Potentiometers Procurement Notes

Verify component status as the X9118TV14-2.7 is listed as obsolete or end-of-life by the manufacturer. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing PCB footprints and design specifications before procurement.

Digital Potentiometers Selection Notes

Select this component when a high-resolution 100 kOhm digital potentiometer with I2C interface is required. Verify that the 1024 tap resolution meets system precision needs. Check that the 2.7 V to 5.5 V supply range aligns with the target application voltage. Consider the TSSOP-14 package constraints for board layout.

Digital Potentiometers Part Context

This part belongs to the X9118 series of single-channel digital potentiometers. It shares architectural similarities with other X911x family members but differs in interface type; for example, the X9118 uses I2C while variants like X9110 use SPI. The suffix -2.7 indicates the minimum operating voltage threshold.

Digital Potentiometers Replacement Considerations

Direct replacements may be limited due to the obsolete status. Evaluate alternative digital potentiometers with I2C interfaces and similar resistance values. Ensure pinout compatibility if substituting within the same package footprint.
