MAS6512
Capacitive Sensor Signal Interface IC
• Single or Dual Capacitance Sensors • Low Voltage Operation • Low Power Consumption • On Chip Temperature Sensor • Internal Clock Oscillator • 16-Bit Ratiometric ∆Σ CDC • EEPROM Calibration Memory • Serial Interface
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 (∆Σ) conversion technique. The output data from the ∆Σ-modulator is processed by an on-chip decimator filter, producing a high resolution conversion result.
