Analog Devices AD5172/AD5173 Datasheet
The Analog Devices AD5172/AD5173 are dual-channel, 256-position, one-time programmable (OTP) digital potentiometers that employ fuse link technology. These devices offer a cost-effective alternative to EEPROM-based memory for users who do not need to program the resistance setting more than once.
The components feature end-to-end resistances of 2.5 kΩ, 10 kΩ, 50 kΩ, and 100 kΩ in compact MSOP-10 packages. They operate with a single supply voltage ranging from 2.7 V to 5.5 V and include a unique temporary OTP overwrite feature that allows for new adjustments even after the fuse has been blown.
