AD7376ARUZ50-REEL7

Digital Potentiometers Overview

The AD7376ARUZ50-REEL7 is a single-channel, high-voltage digital potentiometer manufactured by Analog Devices Inc. It features a nominal resistance of 50 kΩ with ±30% tolerance and 128 tap positions controlled via a 3-wire SPI-compatible serial interface. 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. Key electrical parameters include a typical bandwidth of 90 kHz at midscale, a settling time of 4 µs, and a shutdown supply current of less than 1 µA. It operates within an extended industrial temperature range of −40°C to +85°C.

Digital Potentiometers Feature Summary

• High-voltage capability supporting up to 30 V single-supply or ±15 V dual-supply operation
• 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 specific ordering suffix '-REEL7' corresponds to the reel packaging format required for automated assembly processes. Confirm that the 50 kΩ resistance value aligns with the circuit design requirements, as the AD7376 family also offers 10 kΩ and 100 kΩ variants. Ensure compatibility with the 3-wire serial protocol timing specifications during integration.

Digital Potentiometers Selection Notes

Select this component when high voltage handling and solid-state reliability are required to replace mechanical potentiometers. The 50 kΩ option provides a balance between bandwidth (90 kHz) and power consumption compared to the 100 kΩ variant. Consider the volatile memory nature of the wiper setting; utilize the SHDN pin for programmable preset functionality if EEPROM retention is not available in the system architecture.

Digital Potentiometers Part Context

This part belongs to the AD7376 series of iCMOS™ high-performance digital potentiometers. It is functionally equivalent to mechanical pots but offers enhanced resolution and dynamic controllability. The 'RUZ' designation indicates the 14-lead TSSOP package, while the '50' specifies the 50 kΩ resistance value within the product line.
