AD5235BRUZ25-RL7

The AD5235BRUZ25-RL7 is a digital potentiometer manufactured by Analog Devices Inc./Maxim Integrated. Digital potentiometers, also known as digital variable resistors or digipots, are electronic components that emulate the functionality of mechanical potentiometers using digital control signals. The AD5235BRUZ25-RL7 is a single-channel, 1024-position digital potentiometer with non-volatile memory, making it suitable for various analog signal processing and control applications.

Key Features:

• Single Channel: Features a single potentiometer channel, allowing it to adjust the resistance of one signal path or control one parameter in analog circuits.

• 1024-Position Resolution: Provides high resolution with 1024 selectable resistance positions, allowing for fine adjustment and precise control of analog signals or parameters.

• Digital Interface: Controlled via a digital interface (such as SPI or I2C), enabling easy interfacing with microcontrollers, DSPs (Digital Signal Processors), and other digital control systems.

• Non-Volatile Memory: Includes non-volatile memory to store the wiper position, ensuring that the resistance settings are retained even when power is removed or the device is reset.

• Low Temperature Coefficient: Exhibits low temperature coefficient of resistance (TCR), minimizing variations in resistance over temperature and enhancing stability in temperature-sensitive applications.

• Wide Supply Voltage Range: Supports a wide supply voltage range, allowing operation from various power sources and voltage levels commonly found in electronic systems.

• Low Power Consumption: Consumes low power during operation, making it suitable for battery-powered and energy-efficient applications.

• Compact Package: Packaged in a compact and surface-mountable package, facilitating easy integration into PCB designs and space-constrained applications.

Applications:

• Analog Signal Conditioning: Used for adjusting gain, offset, or filtering characteristics in analog signal conditioning circuits, instrumentation amplifiers, and sensor interfaces.

• Digital-to-Analog Conversion: Integrated into digital-to-analog converter (DAC) circuits for fine-tuning output voltage or current levels in audio systems, industrial control systems, and test equipment.

• Variable Gain Amplifiers: Employed in variable gain amplifier (VGA) circuits for adjusting the amplification factor or gain control in RF (Radio Frequency) communication systems and baseband signal processing.

• Voltage Control: Utilized in voltage control applications such as voltage-controlled oscillators (VCOs), frequency synthesizers, and phase-locked loops (PLLs) for precise voltage tuning and frequency control.

• Calibration and Trim: Deployed for calibration and trim adjustments in electronic circuits and systems requiring precise adjustment of resistance values or analog parameters.

• Automotive Electronics: Integrated into automotive electronics systems such as electronic throttle control, motor drive systems, and power management modules for electronic calibration and control.
