PCap04 Capacitance-to-Digital Converters

ScioSense PCap04 Capacitance-to-Digital Converters (CDCs) feature an integrated Digital Signal Processor (DSP) for on-chip data post-processing. The converter front-end is based on the PICOCAP principle, which offers outstanding flexibility concerning power consumption, resolution, and speed. These CDCs cover a wide capacitance input range from a few femtofarads to several hundred nanofarads. The on-chip DSP allows implementing sensor algorithms like linearization and temperature compensation, with data output in a digital (SPI or I 2 C) or analog (PDM/PWM) way. ScioSense PCap04 CDCs feature up to six capacitors in grounded connection, three capacitors in floating connection, and an integrated guard driver. Typical applications include position, pressure, force, proximity, acceleration, humidity, inclination, angle, and level sensors.
