X93256WV14I-2.7

Digital Potentiometers Overview

The X93256WV14I-2.7 is a dual digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation, housed in a 14-TSSOP surface-mount package. It integrates two independent circuits, each featuring 32 taps and a resistance value of 12.5k ohms with ±25% tolerance. The device utilizes an Up/Down (U/D, INC, CS) serial interface for wiper position control and employs non-volatile memory to retain settings without power. Operating within a supply voltage range of 2.7V to 5.5V, it supports a typical temperature coefficient of ±300ppm/°C and functions reliably across an industrial temperature range of -40°C to 85°C.

Digital Potentiometers Feature Summary

• Dual circuit architecture providing two independent digitally controlled potentiometers within a single package
• Non-volatile memory storage ensures retention of wiper positions during power-off conditions
• Standardized serial interface using Up/Down, Increment, and Chip Select signals for straightforward digital control

Digital Potentiometers Applications

• Data acquisition systems requiring adjustable signal conditioning
• Industrial process control applications needing precise gain or offset adjustments
• Audio equipment utilizing digital volume or tone control mechanisms

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to the presence of counterfeit risks in the electronic components market. Confirm that the specific suffix matches the required interface and packaging specifications. Ensure compliance with relevant environmental regulations applicable to your region before integration into final products.

Digital Potentiometers Selection Notes

Select this component when a design requires two isolated variable resistors controlled via simple serial logic rather than complex protocols like SPI or I2C. Consider the 12.5k ohm resistance value and 32-tap resolution against application requirements. Evaluate the 14-TSSOP footprint constraints and thermal performance characteristics relative to the host system's layout capabilities.

Digital Potentiometers Part Context

This part belongs to the X93256 family of dual XDCPs from Renesas, designed for cost-sensitive applications requiring multiple adjustable parameters. It complements single-channel variants by offering integrated dual functionality, reducing board space and component count in designs necessitating simultaneous adjustment of two distinct electrical parameters.

Digital Potentiometers Replacement Considerations

Direct substitutes include other dual XDCP models from Renesas with compatible pinouts and interface types. Verify equivalent resistance values, tap counts, and voltage ranges when evaluating cross-references to ensure functional parity in the target application.
