The MVCT017 is a programmable capacitance-to-digital converter interface, designed to be easily integrated with capacitive sensors. The chip features very fast measurement times, low operating power, and very low standby currents, making it very suitable for low-power and portable applications. Also, the ASIC includes a high-accuracy temperature sensor and a DAC to convert the calibrated measurements into an analog voltage that is proportional to the supply voltage.
