AD7376AN50

Digital Potentiometers Overview

The AD7376AN50 is a high-voltage, 128-position digital potentiometer manufactured by Analog Devices Inc. It operates with single-supply voltages from 20 V to 30 V or dual supplies from ±10 V to ±15 V. The device features a 3-wire SPI-compatible serial interface and utilizes iCMOS process technology. Key electrical specifications include a typical Total Harmonic Distortion (THD) of 0.006% at 1 kHz, a bandwidth of 470 kHz for the 10 kΩ version, and a shutdown supply current of less than 1 µA. It provides programmable preset capabilities via the SHDN pin and operates over an extended industrial temperature range of −40°C to +85°C.

Digital Potentiometers Procurement Notes

Verify the package type associated with the 'AN' suffix against the manufacturer's ordering guide. Confirm that the required resistance value (10 kΩ, 50 kΩ, or 100 kΩ) matches the specific part number variant needed for the design. Ensure the operating environment stays within the specified −40°C to +85°C temperature range.

Digital Potentiometers Selection Notes

Select the AD7376AN50 when high voltage tolerance and low distortion are required in a digital potentiometer. Choose the 10 kΩ version for higher bandwidth (470 kHz) and faster settling times, while the 50 kΩ and 100 kΩ versions offer lower power consumption. Consider the programmable preset feature if EEPROM solutions are too costly or complex for the application.

Digital Potentiometers Part Context

The AD7376 is part of Analog Devices' high-performance digital potentiometer family. It serves as a solid-state replacement for mechanical potentiometers, offering enhanced resolution and dynamic controllability. The device is available in 14-lead TSSOP and 16-lead wide body SOIC packages, designed for applications requiring precise electronic adjustment of resistance or voltage division.
