Analog Devices AD5171 Digital Potentiometer Datasheet

The AD5171 is a 64-position, one-time programmable (OTP) digital potentiometer that uses fuse link technology to achieve memory retention of resistance setting function. OTP is a cost-effective alternative over the EEMEM approach for users who do not need to reprogram new memory setting in the digital potentiometer. This device performs the same electronic adjustment function like most mechanical trimmers and variable resistors.

About this manual

The AD5171 is a 64-position, one-time programmable (OTP) digital potentiometer that employs fuse link technology to achieve permanent memory retention of resistance settings. It serves as a low-cost alternative to EEPROM-based approaches for applications requiring fixed adjustments after initial setup, such as system calibration and automotive electronics.

Frequently asked questions

What is the primary function of the AD5171?

It is a 64-position, one-time programmable (OTP) digital potentiometer that employs fuse link technology to achieve memory retention of resistance settings.

How does the OTP feature work?

During OTP activation, a permanent fuse blown command is sent after the final value is determined, freezing the wiper position so it will not change regardless of supply variations.

Is factory programming software available?

Yes, Analog Devices offers device programming software that operates across Windows 95 to XP platforms.
