X95840UV20I-2.7

Overview

The X95840UV20I-2.7 is a non-volatile digital potentiometer from the Renesas X9584 series, featuring three independent channels within a single package. It utilizes an I2C serial interface for communication and offers 10 kΩ resistance with linear taper characteristics. The device contains 256 tap positions per channel and includes non-volatile memory to retain wiper settings during power cycles. Operating on a supply voltage range of 2.7V to 5.5V, it supports surface-mount TSSOP packaging with 20 pins and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Three-channel configuration with 10 kΩ resistance and linear taper
• Non-volatile memory retains wiper position after power loss
• Serial I2C interface for control and data transfer
• 256 discrete tap positions per potentiometer

Applications

• Audio volume and tone control circuits
• Programmable gain amplifier adjustments
• Voltage reference trimming in sensor interfaces
• System calibration and parameter adjustment

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm specific ordering suffixes match required voltage and package variants. Check current availability status as inventory levels fluctuate. Ensure compliance with relevant regional regulatory standards prior to integration into final products.

Selection Notes

Select this model when multi-channel digital adjustment is required without external microcontrollers for storage. Compare against volatile alternatives if power-down retention is unnecessary. Verify I2C address compatibility with existing system bus architecture. Ensure operating voltage requirements align with the 2.7V to 5.5V specification range.

Part Context

This component belongs to the X9584 family of non-volatile digital potentiometers. It shares architectural similarities with other members like the X9583 and X9584, differing primarily in channel count and pinout configurations. The series is designed for applications requiring precise, software-controlled resistance adjustment with persistent state management.

Replacement Considerations

Direct replacements include other X9584 series variants such as X9583 or X9584 models with compatible pinouts. Cross-reference specifications for resistance tolerance, temperature coefficient, and interface protocol before substitution.
