PCAP02 Capacitance-to-Digital Converter
Low power capacitance-to-digital converter with wide input range (from fF to nF) and versatile configuration options. PCap02 can be configured for highest sampling rates up to 500kHz, lowest current consumption down to 2µA or lowest noise of 15 aF (rms). The internal signal processor allows for power-efficient and fast calculations, e.g. for sensor linearization or complex arithmetics.
PCAP01 Capacitance-to-Digital Conversion Digital Signal Processor
PCapØ1 is a dedicated Capacitance-to-Digital Conversion Digital Signal Processor. Its front end is based on acam‘s patented 4→ principle. This conversion principle offers high resolution at conversion times as short as 2 µs. Customers benefit from outstanding flexibility for optimizing power consumption, resolution and speed.
PCAP04 Capacitance-to-Digital Converter
PCap04 is a capacitance-to-digital converter (CDC) with integrated digital signal processor (DSP) for on-chip data post-processing. Its front end is based on the PICOCAP principle. This conversion principle offers outstanding flexibility with respect to power consumption, resolution and speed. Further, PCap04 covers a wide capacitance input range from a few femtofarads up to several hundreds of nanofarads. It is easy to configure the PCap04 for different capacitance measurement tasks, i.e. single as well as differential sensors in both, grounded or floating connection. The on-chip DSP allows to implement sensor algorithms like linearization and temperature compensation, with data output in a digital (SPI or IIC) or analog (PDM/PWM) way.
