PCAP02AE

ADCs/DACs - Special Purpose Overview

The PCAP02AE is a capacitance-to-digital converter manufactured by ScioSense, housed in a 32-QFN (5x5) package. It supports I²C and SPI interfaces with a measurement speed of up to 500k samples per second. The device measures capacitance values ranging from femtofarads to nanofarads using a charge/discharge time measurement principle. Internal reference capacitors are integrated for calibration, enabling accurate measurements without external components.
