PCap01
Overview
PCapØ1 is a dedicated Capacitance-to-Digital Conversion Digital Signal Processor. Its front end is based on acam‘s patented ® 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.
The PCap01A can be used for grounded single and differential sensors as well as for floating single and differential sensors. With grounded capacitors the stray capacitance inside the chip will be pensated. With floating capacitors, further to the internal stray capacitance, the external stray capacitances as well get pensated. Additionally, the temperature can be measured by means of internal thermistors or external ones (platinum or others). Before loading some firmware to it, the chip is not pletely operable. Data will end up in ALU instead of being transferred to processor and/or output. Under this circumstance, we chose to write a bined data sheet...
