.. C a pa c i t i v e S e n s o r I n t e r f a c e D a ta s h e e t 1 General Description AS1716 is an analog front end specifically designed for unbiased Capacitive Sensors, as for instance Knock Sensors in Automotive, to be interfaced with Analog Digital Converters with Sample and Hold input stages. The device provides differential inputs, a 1st order low pass filter to cutoff the high frequency noise ponents, differential to single ended conversion, programmable gain stage and a 2 pole low pass Multiple Feedback Filter. The Knock Sensor is a Piezo Electric device that generates a voltage if it is stressed. It senses knock and transmits information to the...
