Frequently asked questions

What is the main feature of the AD5172/AD5173?

They are one-time programmable (OTP) digital potentiometers that use fuse link technology to achieve memory retention of resistance setting.

Can the resistance be adjusted after OTP activation?

Yes, a unique temporary OTP overwrite feature allows for new adjustments even after the fuse has been blown, though the setting is restored during subsequent power-up.

What operating systems are supported by the programming software?

The device programming software runs on Windows NT, 2000, and XP operating systems.
