R(ab): 10 kOhm; V(cc): -0.3 to +7V; 256-position one-time programmable dual-channel I2C digital potentiometer. For system calibrations, electronic level settings, mechanical trimmers replacement in new designs, permanent factory PCB setting, etc.
The AD5172/AD5173 are dual channel, 256-position, one-time programmable (OTP) digital potentiometers1 that employ fuse link technology to achieve memor y retention of resistance setting. OTP is a cost-effective alternative to EEMEM for users who do not need to program the digital potentiometer setting in memor y more than once. This device performs the same electronic adjustment function as mechanical potentiometers or variable resistors with enhanced resolution, solid-state reliability, and superior low temperature coefficient performance. 2
