AD5171BRJZ10-R7

AD5171BRJZ10-R7 is a 64-position OTP digital potentiometer. It uses fuse link technology to achieve the memory retention of the resistance setting function. OTP is a cost-effective alternative over the EEMEM approach for users who do not need to reprogram new memory settings in the digital potentiometer. This device performs the same electronic adjustment function as most mechanical trimmers and variable resistors. It is programmed using a 2-wire, I²C®- compatible digital control. It allows unlimited adjustments before permanently setting the resistance value. It is used in applications such as system calibrations, electronics level settings, mechanical trimmers and potentiometer replacements, automotive electronics adjustments, gain control and offset adjustments, transducer circuit adjustments, and programmable filters up to 1.5MHz BW.
