DESCRIPTION
MAS6512 capacitive sensor signal Interface IC can interface both single and dual capacitance sensors.
It uses a 16-bit Capacitance-to-Digital Converter (CDC), which employs a delta-sigma (ΔΣ) conversion technique. The output data from the ΔΣ-modulator is processed by an on-chip decimator filter, producing a high resolution conversion result. The converter is run by an internal clock oscillator making an external converter clock unnecessary.
