PCap04中文资料Low-power CDC with 32-bit DSP and guarding数据手册ams-OSRAM规格书

描述 Description

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 ams 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.
