ANALOG DEVICES AD5171 handbook (1)
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.
