X9455TV24I-2.7

Digital Potentiometers Overview

The X9455TV24I-2.7 is a dual two-wiper Digitally Controlled Potentiometer (XDCP) from the XDCP series, manufactured by Renesas Electronics Corporation. It integrates two independent potentiometers on a monolithic CMOS IC, each featuring 256 resistive tap points for 0.4% resolution. The device operates within a supply voltage range of 2.7V to 5.5V and supports a total resistance of 100kΩ. It utilizes a 2-wire serial interface or an Up/Down interface for wiper control. Non-volatile memory stores wiper positions, enabling power-on recall. The component is housed in a 24-lead TSSOP package.

Digital Potentiometers Feature Summary

• Dual two-wiper architecture with 256 resistor tap points per potentiometer
• Non-volatile storage of wiper positions with power-on recall capability
• Supports both 2-wire serial interface and Up/Down interface modes
• Hardware write protect input (WP) for data security

Digital Potentiometers Applications

• Programming bias voltages in electronic circuits
• Configuring window comparators
• Implementing three-resistor programmable networks

Digital Potentiometers Procurement Notes

This component is designated as Not Recommended for New Designs with no recommended replacement provided by the manufacturer. Verification of current availability and lifecycle status is required before integration into new projects due to its obsolete classification.

Digital Potentiometers Selection Notes

Select this part for applications requiring dual independent potentiometers with non-volatile position retention. Ensure the design accommodates the 2.7V to 5.5V supply range and the 100kΩ resistance value. Verify compatibility with either the 2-wire serial protocol or the Up/Down interface logic based on system constraints.

Digital Potentiometers Part Context

The X9455 belongs to the XDCP family of digitally controlled potentiometers. This specific variant, X9455TV24I-2.7, denotes the 100kΩ resistance version in a 24-lead TSSOP package with industrial temperature rating (-40°C to +85°C). It is part of a broader lineup including 2.8kΩ, 10kΩ, and 50kΩ variants.

Digital Potentiometers Replacement Considerations

No recommended replacement is specified by the manufacturer. Designers should evaluate parametrically similar dual-channel digital potentiometers with non-volatile memory and compatible interface protocols.
