PICOCAP Capacitive Sensing
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.
ams signal converters contain four or eight signal channels, and can be dynamically programmed in-process by means of multiple amplification levels. This makes them very well suited for multi-channel sensor systems in applications with dynamic amplification and a high sensor bandwidth. All the converters small: they are available in space-saving (Q)SOP packages or as Chip-on-Board(COB) packages.
PICOSTRAIN Resistive Sensing
The Resistance-to-Digital Converters (RDCs), based on the pure digital PICOSTRAIN measuring principle, combine very high precision with very low power consumption. Featuring an on-chip CPU, the PICOSTRAIN devices enhance the performance of resistive pressure sensors, force sensors, weighing scales and many other applications.
Battery Sensor Interfaces
Zero-offset battery sensor interfaces for current and voltage sensing offer high accuracy. All have a wide dynamic range. Shunt current sensing can take place at the either the positive or negative pole.
