AD7376ARUZ100

Digital Potentiometers Overview

The AD7376ARUZ100 is a single-channel, high-voltage digital potentiometer manufactured by Analog Devices Inc. It features 128 tap positions with a nominal resistance of 100 kΩ and ±30% tolerance. The device operates on a single supply from 4.5 V to 33 V or dual supplies from ±4.5 V to ±16.5 V. It utilizes a 3-wire SPI-compatible serial interface for control. Key electrical parameters include a typical bandwidth of 50 kHz at 100 kΩ, a settling time of 4 µs, and a shutdown current of less than 1 µA. The component is housed in a 14-lead TSSOP package and supports an extended industrial operating temperature range from -40°C to +85°C.

Digital Potentiometers Feature Summary

• High voltage operation supporting up to 30 V single-supply or ±15 V dual-supply configurations
• 128-position resolution with linear taper and programmable preset via SHDN pin
• Low power consumption with shutdown mode drawing less than 1 µA
• 3-wire SPI-compatible serial interface with daisy-chain capability

Digital Potentiometers Applications

• High voltage digital-to-analog converters (DAC)
• Programmable gain and offset adjustment circuits
• Actuator control systems
• Audio volume control applications
• Mechanical potentiometer replacement

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and reel specifications. Confirm that the required resistance value matches the '100' designation within the part number. Ensure compatibility with the 14-lead TSSOP footprint during PCB layout planning.

Digital Potentiometers Selection Notes

Select this component when high voltage handling and solid-state reliability are required over mechanical alternatives. Consider the 100 kΩ resistance value for lower power consumption applications, noting that bandwidth decreases compared to lower resistance variants. Verify that the system can accommodate the volatile memory nature of the wiper position upon power-up.

Digital Potentiometers Part Context

This device belongs to the AD7376 family of iCMOS digital potentiometers. It serves as a direct electronic replacement for mechanical pots, offering enhanced resolution and programmability. The ARUZ100 variant specifically denotes the 100 kΩ resistance option packaged in a 14-lead TSSOP form factor suitable for surface-mount assembly.

Digital Potentiometers Replacement Considerations

Direct replacements within the same family include the AD7376ARWZ100, which offers identical electrical characteristics but utilizes a 16-lead SOIC_W package. Designers must account for the physical footprint differences when substituting between the TSSOP and SOIC packages.
