The X9250UV24Z-2.7 is a Quad Digital Controlled Potentiometer (XDCP) from Intersil Corporation. It integrates four independent digitally controlled potentiometers into a single chip. Each potentiometer provides 256 wiper tap positions, offering precise adjustment and control of resistance values. The device operates on a 2.7V power supply, making it suitable for low-voltage applications.

Applications:

• LCD screen adjustment and calibration
• Volume control in audio equipment
• Brightness control in lighting systems
• Gain control in amplifiers
• Offset trimming in sensor circuits

Features:

• Quad digitally controlled potentiometers
• 256 wiper tap positions per potentiometer
• 2.7V power supply operation
• I2C serial interface for digital control
• Non-volatile storage of wiper positions
• Low power consumption
• Wide operating temperature range

Benefits:

• Precise adjustment and control of resistance values
• Digital control eliminates the need for manual adjustments
• Non-volatile storage retains the wiper positions even when power is removed.
• I2C interface simplifies communication with microcontrollers.
• Low power consumption is suitable for battery-powered applications.
• Compact package saves board space.

Additional Details:

The X9250UV24Z-2.7 uses an I2C serial interface to control the wiper positions of the four potentiometers. The resistance value between the wiper and each end of the potentiometer is digitally programmable, providing a wide range of adjustable resistance values. Each potentiometer can be independently controlled, making the device highly versatile. The non-volatile memory ensures that the wiper positions are retained even when the power is turned off. The device is available in a TSSOP package.
