For users who do not need to program the digital potentiometer setting in memory more than once, the OTP feature is a cost-effective alternative to EEMEM. The AD5170 performs the same electronic adjustment function as mechanical potentiometers or variable resistors with enhanced resolution, solid-state reliability, and superior low temperature coefficient performance.

ture range of -40C to +125C. Besides their unique OTP features, the AD5172/AD5173 lend themselves well to other general-purpose digital potentiometer applications due to their programmable preset, superior temperature stability, and small form factor. The AD5170 (Reference 6) is a two-time programmable 8-bit digital potentiometer, and a functional diagram is shown in Figure 6. Note that a second fuse array is provided to allow "second chance" programmability. Like the AD5172/AD5173, there is unlimited programmability before making the permanent setting. The electrical characteristics of the AD5170 are similar to the AD5172/AD5173.
