X9259UV24I

Digital Potentiometers Overview

The X9259UV24I is a quad digital potentiometer IC from the XDCP series, manufactured by Renesas Electronics Corporation. It features four independent potentiometers with linear taper and 256 taps each, providing a resistance value of 50 kOhms per channel. The device utilizes an I2C serial interface for control and incorporates non-volatile memory to retain wiper settings upon power loss. It operates within a supply voltage range of 4.5 V to 5.5 V, typically at 5 V, with a maximum operating current of 3 mA. The component is housed in a 24-TSSOP surface-mount package and supports an industrial temperature range from -40°C to +85°C.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 50 kOhm digital potentiometers
• 256-tap resolution with linear taper for precise resistance adjustment
• Non-volatile memory retains wiper position during power-off cycles
• I2C serial interface allows for multi-device addressing capabilities

Digital Potentiometers Applications

• Programmable gain amplifiers requiring adjustable resistance ratios
• Voltage reference trimming in precision measurement systems
• Digital volume control circuits in audio processing equipment
• Adaptive biasing networks in sensor signal conditioning

Digital Potentiometers Procurement Notes

Verify the specific suffix 'I' against official datasheets to confirm the industrial temperature grade (-40°C to +85°C) and ensure compatibility with the 24-TSSOP package. Confirm RoHS compliance status as manufacturing updates may affect environmental declarations. Cross-reference the manufacturer part number with authorized distributors to validate current production status and availability.

Digital Potentiometers Selection Notes

Select this component when a quad-channel digital potentiometer with non-volatile storage is required. Ensure the system design accommodates the 50 kOhm resistance value and 256-step resolution. Verify that the microcontroller provides a compatible I2C interface. Consider the ±20% tolerance and ±300ppm/°C temperature coefficient for circuit accuracy requirements.

Digital Potentiometers Part Context

This part belongs to the X9259 family of quad digital potentiometers. Variants within the family differ primarily in packaging (e.g., SOIC vs. TSSOP), interface type (I2C vs. SPI vs. 2-Wire), and resistance values. The UV24 designation specifically indicates the 50 kOhm resistance value and the 24-pin TSSOP package form factor.

Digital Potentiometers Replacement Considerations

X9259UV24IZ is listed as a parameter-equivalent alternative. Verify pinout compatibility and electrical specifications before substitution.
