AD5171 THEORY OF OPERATION SCL SDA The AD5171 allows unlimited 6-bit adjustments, except for the one-time programmable, set-and-forget resistance setting. OTP technology is a proven, cost-effective alternative over EEMEM in one-time memory programming applications. The AD5171 employs fuse link technology ...
