Analog Devices AD5171 Digital Potentiometer Datasheet
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.

Questions answered in these manuals
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.
How is the AD5171 programmed?
It is programmed using a 2‑wire I²C‑compatible digital control, allowing unlimited adjustments before the OTP fuse is blown to set the resistance permanently.

What package does the AD5171 use?
The AD5171 is supplied in a compact 8‑lead SOT‑23 package.

How many AD5171 devices can share the same I²C bus?
Up to two devices can be addressed using the extra address pin.
How long does the OTP programming take?
The OTP program time is 400 ms.
