X95820WV14IZ-2.7

Overview

The X95820WV14IZ-2.7 is a single-channel non-volatile digital potentiometer from the Renesas XDCP series, housed in a 14-TSSOP package. It features a resistance value of 10 kΩ with 64 taps and utilizes an I2C serial interface for control. The device operates within a supply voltage range of 2.7V to 5.5V and supports a wide operating temperature range from -40°C to +85°C. Key electrical characteristics include a typical wiper contact resistance of 150 Ω, a tolerance of ±20%, and a temperature coefficient of ±300ppm/°C.

Feature Summary

• Non-volatile memory retains wiper position settings upon power loss
• I2C serial interface enables simple two-wire communication
• Linear taper configuration provides uniform resistance adjustment

Applications

• Industrial process control systems requiring adjustable gain or reference voltages
• Consumer electronics for user-adjustable audio or lighting levels
• Embedded sensor calibration circuits

Procurement Notes

Verify component authenticity through authorized distributors as this part may be discontinued. Confirm that the specific suffix matches the required voltage and package specifications. Request original manufacturer documentation to validate RoHS compliance and lot traceability before finalizing procurement orders.

Selection Notes

Select this component when a single-channel digital potentiometer with I2C connectivity is required. Ensure the 10kΩ resistance and 64-tap resolution meet circuit precision needs. Verify that the 14-TSSOP footprint fits the PCB layout constraints and that the -40°C to +85°C temperature range covers the operational environment.

Part Context

This component belongs to the X9582 family of non-volatile digital potentiometers designed by Renesas Electronics. These devices are engineered to replace mechanical potentiometers in applications where size, reliability, and programmability are critical. The XDCP technology integrates EEPROM storage directly onto the silicon die.

Replacement Considerations

Check for direct pin-compatible replacements within the same X9582 series or verify if the X9420 series offers equivalent SPI-based functionality if interface flexibility is acceptable.
