X95820UV14I-2.7T1

Overview

The X95820UV14I-2.7T1 is a non-volatile digital potentiometer from the Renesas X9582 series, housed in a 14-pin TSSOP package. It features a single channel with a resistance value of 10 kΩ and 1024 tap positions for precise adjustment. The device operates on a supply voltage range of 2.7V to 5.5V and utilizes an I2C serial interface for communication. It includes non-volatile memory to retain wiper settings during power-off conditions.

Feature Summary

• Single-channel digital potentiometer with 10 kΩ nominal resistance
• 1024 discrete tap positions for high-resolution control
• Non-volatile memory retains wiper position after power loss
• I2C serial interface compatible with standard protocols

Applications

• Audio volume and tone control circuits
• Programmable gain amplifier offset adjustments
• Voltage reference trimming in sensor interfaces
• Industrial process control parameter setting

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lot codes and date codes match current production standards. Check for RoHS compliance status as older batches may differ. Ensure packaging integrity upon receipt to prevent moisture damage prior to reflow soldering.

Selection Notes

Select this model when a single-channel, non-volatile digital potentiometer with I2C control is required. The 10 kΩ resistance and 1024 taps suit applications needing moderate resolution. Verify that the system logic levels are compatible with the I2C interface voltage requirements within the 2.7V to 5.5V operating range.

Part Context

This component belongs to the X9582 family of non-volatile digital potentiometers. It shares architectural similarities with other members like the X9583 and X9584, differing primarily in channel count and specific interface configurations. The 'UV' suffix indicates the TSSOP package type, while 'I' denotes industrial temperature range operation.

Replacement Considerations

Direct pin-to-pin replacements include other X9582 series variants such as X95820WV14I-2.7. Ensure substitute parts maintain the same non-volatile memory technology and I2C addressability if multiple devices are used on the same bus.
