X95840UV20IZ-2.7

Overview

The X95840UV20IZ-2.7 is a non-volatile digital potentiometer from the Renesas X9584 series, housed in a 20-pin TSSOP package. It integrates three independent channels, each offering 10 kΩ resistance with linear taper characteristics and 256 configurable tap positions. The device utilizes a serial I2C interface for communication and operates within a supply voltage range of 2.7 V to 5.5 V. Designed for surface-mount installation, it functions reliably across an industrial temperature range of -40°C to +85°C, featuring a typical temperature coefficient of 4 ppm/°C.

Feature Summary

• Three-channel architecture with 10 kΩ resistance per channel
• Non-volatile memory retains wiper position upon power loss
• Serial I2C interface for control and data transfer
• 256 tap positions providing precise resistance adjustment

Applications

• Audio volume and tone control circuits
• Programmable gain amplifier biasing
• Voltage reference trimming
• Industrial process control calibration

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix '2.7' indicates the required operating voltage range. Check current availability status as electronic components may be subject to lifecycle changes or discontinuation notices.

Selection Notes

Select this model when three independent digital potentiometers are required in a single package. Ensure the I2C interface compatibility with the host microcontroller. Verify that the 10 kΩ resistance value and 256-step resolution meet the application's precision requirements compared to higher or lower tap counts.

Part Context

This component belongs to the X9584 family of non-volatile digital potentiometers. The 'X95840' designation typically refers to the base part number variant, while 'UV20IZ' specifies the 20-pin TSSOP package and industrial temperature grade. The '2.7' suffix denotes the minimum operating voltage capability.

Replacement Considerations

Cross-reference with other X9584 series variants such as X9583 or X9585 for different channel counts. Verify pinout compatibility before substituting with similar I2C digital potentiometers from other manufacturers.
