ISL95810WIRT8Z-T

Digital Potentiometers Overview

The ISL95810WIRT8Z-T is a non-volatile digital potentiometer from the XDCP series, manufactured by Renesas Electronics. It features a single circuit with a resistance value of 10 kΩ and 256 taps. The device utilizes an I2C serial interface for communication and operates within a supply voltage range of 2.7V to 5.5V. It is housed in an 8-TDFN (3x3 mm) package with a bare pad. The component supports linear taper characteristics and maintains data retention through non-volatile memory.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper position after power loss
• I2C compatible serial interface for control
• 256 discrete tap positions for precise adjustment
• 10 kΩ nominal resistance with ±20% tolerance

Digital Potentiometers Applications

• Audio volume control circuits
• Gain adjustment in signal conditioning paths
• Voltage reference trimming
• Calibration settings in embedded systems

Digital Potentiometers Procurement Notes

Verify component authenticity due to end-of-life status. Check RoHS compliance markings as older batches may differ. Confirm package orientation and pin 1 identification on the 8-TDFN housing. Ensure I2C address configuration matches system requirements before integration.

Digital Potentiometers Selection Notes

Select this model for applications requiring persistent resistance settings without external battery backup. Compare against ISL95810 variants if different resistance values or packaging options are needed. Verify I2C bus speed compatibility with the host controller. Consider thermal performance within the -40°C to 85°C operating range.

Digital Potentiometers Part Context

This part belongs to the ISL95810 family of digital potentiometers. It shares core architecture with other members like ISL95810UIRT8Z but differs in resistance value and specific suffix designations. The WIRT8Z-T suffix indicates tape and reel packaging for surface mount assembly.

Digital Potentiometers Replacement Considerations

Direct substitute: ISL95810UIRT8Z. Verify functional equivalence regarding resistance value and interface protocol. Cross-reference pinouts and electrical specifications before substitution.
