X95840UV20I-2.7T1

Overview

The X95840UV20I-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 features a serial I2C interface for control and communication. It operates within a supply voltage range of 2.7V to 5.5V and supports linear taper characteristics with a typical 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 discrete tap positions per channel
• Non-volatile memory retains wiper position upon power cycle
• Serial I2C interface for simplified system integration
• Linear taper resistance characteristic with low temperature drift

Applications

• Programmable gain amplifiers requiring multi-channel adjustment
• Voltage reference trimming in precision measurement systems
• Audio volume control and equalization circuits
• Industrial process control parameter setting

Procurement Notes

Verify the specific suffix 'U' against official Renesas documentation to confirm material compliance or lead-free status, as distributor listings may vary. Confirm availability status, as similar X9584 variants have been subject to end-of-life notices. Ensure the I2C address configuration matches the target system design before procurement.

Selection Notes

Select this component when multiple independent digital potentiometers are required in a single package to save board space. The 256-tap resolution provides sufficient granularity for most analog control applications. Verify that the I2C bus speed requirements of the host microcontroller are compatible with the device's maximum clock rate specifications found in the datasheet.

Part Context

This part belongs to the X9584 family of non-volatile digital potentiometers. The 'X95840' designation indicates the specific variant with three channels and 256 taps. The 'UV20I' suffix typically denotes the TSSOP-20 package, industrial temperature range, and specific material/lead-free classification. The 'T1' suffix often indicates tape and reel packaging for automated assembly.

Replacement Considerations

Direct replacements include other X9584 series variants such as X9583 or X9585 if pin compatibility and channel count allow. Cross-reference with ISL8205 or AD524x series components for functional equivalents, ensuring I2C protocol and voltage levels match. Verify that any substitute maintains the non-volatile memory feature.
