X95820UV14IZ-2.7T1

Overview

The X95820UV14IZ-2.7T1 is a single digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation, part of the XDCP series. It features a 10 kΩ end-to-end resistance with 64 taps and utilizes an SPI serial interface for control. The device operates on a supply voltage ranging from 2.7V to 5.5V and includes nonvolatile memory to retain wiper positions. Packaged in a 14-pin TSSOP, it supports linear taper configurations and is designed for surface mount installation within an operating temperature range of -40°C to +85°C.

Feature Summary

• Single circuit configuration with 10 kΩ resistance and 64 taps
• SPI serial interface for write, read, and transfer operations
• Nonvolatile data registers for power-on recall of wiper positions
• Operates on VCC supplies from 2.7V to 5.5V

Applications

• Programmable gain amplifiers
• Variable voltage references
• Audio volume control circuits
• Offset voltage trimming in amplifier circuits

Part Context

This component belongs to the X95820 family of low-power, single-channel digital potentiometers. It serves as a solid-state replacement for mechanical potentiometers in applications requiring remote or programmable resistance adjustment. The 'UV' suffix typically denotes the specific package and temperature grade variant within the broader X95820 product line.

Replacement Considerations

Verify pin compatibility and interface protocols when substituting. Ensure the replacement device supports the required 2.7V to 5.5V supply range and SPI communication standards. Check for equivalent nonvolatile memory retention capabilities and tap resolution.
