For the simplest to the most complex designs, our extensive portfolio of amplifiers and comparators enables you to develop low-risk solutions with minimal risk of a forced redesign. These devices are also backed by our client-driven obsolescence practice of continuing to supply a product for as long as possible and while demand for the product exists. We provide thorough documentation that explains how and why these devices work, and you will find that their performance on the bench matches the specifications in their data sheets. Design risk and complexity are further mitigated with integrated features such as on-chip filters to reduce electromagnetic interference, integrated references and hardware enable pins that are available on select devices.
