Schematics gives me choices, but the next selection crashes the app. ### 5/5 — Bonne application pour sélectionner un amplificateur *2016-11-06, version 1.3* Fonctionne très bien sur iOS10 depuis la dernière mise à jour ### 1/5 — Crashing *2015-11-20* Continually crashes no way round it, open and crash ### 4/5 — Ampli *2012-12-11, version 1.0* Très bonne appli, simple et efficace ### 5/5 — Easier to navigate than website *2012-12-10, version 1.0* Sometimes there are too many steps in a semiconductor's website to find the part you are looking for. Then a good app like this one comes along. Simple in design and shows parameters in column form - including automotive status and datasheet PDF. Offers a good filter option with multiple tiers. Straightforward parameters at a glance. ## Frequently asked questions about ST op ### What types of amplifiers can I find using ST op-amps?
