X95840WV20I-2.7

Overview

The X95840WV20I-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 256 tap positions for precise resistance adjustment. The device features a linear taper and utilizes a serial I2C interface for control. It operates within a supply voltage range of 2.7V to 5.5V and maintains functionality across an industrial temperature range of -40°C to +85°C. Key electrical specifications include a nominal resistance of 10 kΩ with ±20% tolerance and a typical temperature coefficient of 4 ppm/°C.

Feature Summary

• Three-channel architecture with 256 taps per channel
• Non-volatile memory retains wiper position upon power loss
• Serial I2C interface for simplified system integration
• Linear taper characteristic with 4 ppm/°C temperature stability

Applications

• Programmable gain amplifiers requiring multi-channel adjustment
• Digital volume control in audio processing systems
• Voltage reference trimming in measurement equipment

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'I-2.7' corresponds to the required industrial temperature grade (-40°C to +85°C) and voltage range (2.7V minimum). Check current availability status as legacy components may have limited stock or end-of-life implications.

Selection Notes

Select this model when multiple independent digital potentiometers are needed in a single package. Ensure the host controller supports the I2C protocol and can handle the device's address configuration. Verify that the 10 kΩ resistance value aligns with the application's impedance requirements and that the 256-step resolution provides sufficient granularity for the intended control loop.

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 X9585, differing primarily in the number of channels and pin count. The X9584 specifically targets applications requiring three isolated potentiometric controls without external memory dependencies.

Replacement Considerations

Direct replacements must match the 20-pin TSSOP footprint, 10 kΩ resistance, 3-channel configuration, and I2C interface. Verify that any substitute part offers equivalent non-volatile storage and meets the same -40°C to +85°C operating temperature range.
