X95820UV14I-2.7

Overview

The X95820UV14I-2.7 is a single-channel digital potentiometer from the Renesas XDCP series, housed in a 14-pin TSSOP package. It features a total resistance of 20 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 includes non-volatile memory to retain wiper position data. It supports optional hardware address selection to allow multiple devices on a single bus.

Feature Summary

• Integrates non-volatile memory to preserve wiper settings across power cycles
• Supports flexible addressing via hardware pins for multi-device bus configurations
• Provides low-noise performance suitable for precision signal processing applications

Applications

• Industrial process control parameter adjustment
• Portable instrumentation calibration
• Audio volume and tone control circuits

Procurement Notes

Verify component authenticity through official Renesas channels or authorized distributors. Confirm manufacturing date codes and lot numbers against current production status. Ensure packaging integrity matches standard tube specifications. Validate RoHS compliance documentation if required by specific regional regulations. Cross-reference datasheet revisions to ensure compatibility with existing design constraints.

Selection Notes

Select this component when a single-channel digital potentiometer with 20 kΩ resistance and 64 resolution steps is required. The I²C interface minimizes pin count compared to SPI alternatives. The wide operating voltage range accommodates various system power rails. Consider the 14-TSSOP footprint for PCB layout constraints. Verify that the ±20% tolerance meets circuit accuracy requirements.

Part Context

This part belongs to the X95820 family of digitally controlled potentiometers. It shares architectural similarities with other XDCP devices but offers specific resistance and tap counts. The UV suffix indicates the 20 kΩ variant, while the 14I denotes the industrial temperature range and package type. It complements Renesas' broader portfolio of analog and mixed-signal components.

Replacement Considerations

Direct substitutes include the X95820WV14I-2.7 (SOIC package) or X95820UV14IZ-2.7 (RoHS compliant). Verify pinout compatibility and electrical parameters before substitution. Package dimensions differ between SOIC and TSSOP variants.
