R(ab): 50 kOhm; V(cc): -0.3 to +7V; Dual 256-position two-time programmable I2C digital potentiometer. For system calibrations, electronic level settings, mechanical trimmers replacement in new designs, permanent factory PCB setting, etc.
The AD5170 is a 256-position, two-time programmable (TTP) digital potentiometer* that employs fuse link technology to enable two opportunities at permanently programming the 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.
