Design Notes from Linear Technology

Linear Technology- April 29, 2015

Linear Tech's Design Note inserts were a popular tear-out feature of EDN's print edition, so we're continuing the practice online (LTC is now part of ADI).

Design Notes are not just ads or datasheets, but provide a deeper insight into the part in question, and frequently offer up a creative, Design Idea-like use.

We hope you continue to enjoy this EDN feature.
