AD5144ABRUZ10 Description

The AD5144ABRUZ10 from Analog Devices Inc. is a quad-channel, 256-tap digital potentiometer designed for precision analog signal adjustment in industrial, automotive, and consumer applications. With a 10kΩ resistance and ±8% tolerance, it offers reliable performance across a wide supply voltage range (2.3V–5.5V single-supply or ±2.25V–2.75V dual-supply). Its I²C interface enables easy integration into digital control systems, while the selectable address feature allows multiple devices to coexist on the same bus. Packaged in a 20-pin TSSOP, this surface-mount device is RoHS3 compliant and suitable for high-density PCB designs.

AD5144ABRUZ10 Features

• Quad-channel configuration: Four independent potentiometers in a single package, reducing board space and complexity.
• Low temperature coefficient (35ppm/°C): Ensures stable performance across temperature variations.
• 55Ω typical wiper resistance: Minimizes signal distortion in voltage-divider and rheostat modes.
• Linear taper: Ideal for linear adjustment applications like gain control and calibration.
• I²C programmable interface: Supports standard (100kHz) and fast (400kHz) modes for flexible communication.
• Selectable address pins (A0–A2): Enables up to eight devices on one bus, simplifying multi-channel systems.

AD5144ABRUZ10 Applications

• Industrial automation: Precision calibration of sensors, actuators, and feedback loops.
• Audio equipment: Volume control, tone adjustment, and parametric equalization.
• Test and measurement: Programmable reference voltage generation and signal conditioning.
• Automotive systems: Infotainment controls and climate system interfaces.
• Power management: Dynamic adjustment of DC-DC converter feedback networks.
