General Description

ams has long time experience in capacitive sensing applications. ams’ ICs perform

high-precision measurements supported by a multitude of diagnosis features (func-

tional safety!). The capacitive ICs are specially designed to work under high electro-

magnetic disturbances (EMC) such as the operation of mobile phones in the car. ams

has long-term experience in safety. EMC-robust designs allow our customers to create

demanding safety-critical applications.
