AD7376ARWZ50

Digital Potentiometers Overview

The AD7376ARWZ50 is a single-channel, high-voltage digital potentiometer manufactured by Analog Devices Inc. It features 128 programmable tap positions with a nominal resistance of 50 kΩ and ±30% tolerance. The device supports dual-supply operation from ±4.5 V to ±16.5 V or single-supply operation from 4.5 V to 33 V. It utilizes an iCMOS process technology and communicates via a 3-wire SPI-compatible serial interface. Key electrical characteristics include a typical total harmonic distortion (THD) of 0.002%, a bandwidth of 90 kHz at mid-scale, and a shutdown supply current of less than 1 µA. The component operates within an extended industrial temperature range of −40°C to +85°C.

• 128-position resolution with 50 kΩ nominal end-to-end resistance
• Low power consumption with programmable shutdown mode drawing less than 1 µA
• SPI-compatible 3-wire serial interface for digital control

Digital Potentiometers Applications

• High voltage DAC implementations
• Programmable gain and offset adjustment circuits
• Actuator control systems
• Audio volume control applications

Digital Potentiometers Procurement Notes

Verify the package type corresponds to the 'W' suffix in the model number, which indicates a 16-lead wide body SOIC. Confirm that the specific revision of the datasheet matches the production lot requirements. Ensure that the operating voltage limits do not exceed the absolute maximum ratings defined in the specifications table.

Digital Potentiometers Selection Notes

Select this component when a high-voltage digital potentiometer is required for precise analog signal conditioning. The 50 kΩ value offers a balance between bandwidth and power consumption compared to the 10 kΩ or 100 kΩ variants. Consider the 16-lead SOIC_W package for PCB layout flexibility if surface mount assembly is preferred over TSSOP options.

Digital Potentiometers Part Context

This part belongs to the AD7376 family of high-performance digital potentiometers. The family includes variants with 10 kΩ, 50 kΩ, and 100 kΩ resistances. The 'ARWZ' designation typically refers to the lead-free, RoHS-compliant version in the 16-lead SOIC package. Evaluation boards such as the EVAL-AD7376EBZ are available for development purposes.

Digital Potentiometers Replacement Considerations

Direct replacements within the same family include the AD7376ARU series for TSSOP packages or other resistance values like AD7376ARWZ100. Verify pin compatibility and thermal resistance specifications when substituting packages.
