X95820UV14IZ-2.7

Overview

The X95820UV14IZ-2.7 is a non-volatile digital potentiometer manufactured by Renesas Electronics Corporation, belonging to the X9582 series. It features a single circuit configuration with a resistance value of 10 kΩ and 64 tap positions. The device utilizes an I2C serial interface for communication and operates within a supply voltage range of 2.7V to 5.5V. Packaged in a 14-TSSOP surface-mount enclosure, it maintains its wiper position through power cycles due to its non-volatile memory architecture.

Feature Summary

• Non-volatile memory retains wiper settings after power loss
• I2C serial interface for simplified system integration
• Single channel with 10 kΩ nominal resistance and 64 taps
• Operates on a 2.7V to 5.5V supply voltage

Applications

• Volume control in audio equipment
• Gain adjustment in signal conditioning circuits
• Voltage reference trimming in measurement systems
• System calibration requiring persistent setting storage

Procurement Notes

This component is identified as obsolete or end-of-life (EOL) in distributor records. Verification of current availability requires checking authorized distributors for remaining stock or evaluating replacement alternatives from the same manufacturer family. Ensure compatibility with existing PCB footprints if sourcing surplus units.

Selection Notes

Select this part when a single-channel digital potentiometer with non-volatile storage and I2C connectivity is required. Verify that the 10 kΩ resistance and 64-tap resolution meet the application's precision needs. Confirm that the operating temperature range of -40°C to 85°C aligns with the environmental conditions of the target design.

Part Context

The X95820UV14IZ-2.7 is part of the X9582 series of non-volatile digital potentiometers. This series typically offers multiple configurations varying in resistance values and package types while maintaining consistent I2C interface protocols and non-volatile memory characteristics across the family.

Replacement Considerations

Due to the EOL status, consider equivalent parts such as the X95820WV14IZ-2.7 or other members of the X9582 series that share the same pinout and electrical specifications. Cross-reference with current production digital potentiometers offering I2C interfaces and non-volatile features.
