PICOCAP Capacitive Sensing description

PICOCAP is a Capacitance-to-Digital Converter (CDC) which uses the patented PICOCAP measuring principle to interface to a broad range of capacitive sensors. The input capacitance can range between a femtoFarad and hundreds of nanoFarads, which means that there is almost no limit to the size of capacitor. The multi-channel CDC provides a high degree of flexibility with respect to accuracy, speed and operating current. A powerful integrated CPU enables on-chip linearization and temperature measurement and compensation.
