X95840WV20I-2.7T1

Overview

The X95840WV20I-2.7T1 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 operates within a supply voltage range of 2.7V to 5.5V and supports serial I2C interface communication. Key electrical specifications include a nominal resistance value of 10 kΩ with a linear taper and a temperature coefficient of 4 ppm/°C. Designed for surface-mount installation, it functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Three-channel architecture with 256-position resolution per channel
• Non-volatile memory retains wiper settings after power loss
• Serial I2C interface for simplified system integration
• Low temperature coefficient of 4 ppm/°C for stability

Applications

• Programmable gain amplifiers
• Voltage reference trimming
• Digital control of analog signal paths

Procurement Notes

Verify the specific suffix 'T1' against official Renesas documentation to confirm tape-and-reel packaging status, as standard listings may indicate tube packaging. Confirm end-of-life or obsolescence status directly with the manufacturer, as availability for this specific part number variant requires current production verification.

Selection Notes

Select this component when a multi-channel, non-volatile digital potentiometer with I2C control is required. Ensure the 10 kΩ resistance value and 256-step resolution meet circuit requirements. Verify that the 2.7V minimum operating voltage aligns with the system power rail and that the TSSOP-20 footprint fits the PCB layout constraints.

Part Context

This part belongs to the X9584 family of non-volatile digital potentiometers. The base model X9584 typically denotes a 3-channel device. The suffix 'WV' often indicates wide voltage operation or specific commercial grade variants, while '20I' specifies the 20-pin TSSOP package and industrial temperature range. The final digits define the resistance value and packaging format.

Replacement Considerations

Direct substitutes within the same family include the X95840WV20IZ-2.7 (tube) if packaging differs. For pin-compatible alternatives, verify other 3-channel non-volatile digital potentiometers with I2C interfaces from Renesas or competitors, ensuring matching resistance values and voltage ranges.
