PCAP04 Capacitance-to-Digital Converter

The PCap04 can be easily configured for various capacitance measurement requirements, including single and differential sensors in both grounded and floating connections.

The on-chip DSP enables the implementation of sensor algorithms like linearization and temperature compensation, with data output options including digital (SPI or IIC) and analog (PDM/PWM).

DIE CAPABILITIES

For customers that are unable to use the QFN24 packaged Pcap04 or require die for their own packaging, ScioSense now offers die in wafer form. Customers requiring less than a wafer for smaller projects or first article builds, PMT (Precision Measurement Technologies) in Clearwater, Florida has wafer packs in 100 and 250 quantities available for quick turnaround. Whether you need just a few hundred or a few thousand, PMT, a ScioSense Technology Center, ships worldwide and can help with your project.\
