The MVCBT015 is a programmable, highly accurate, capacitance-to-digital converter and bridge interface that is designed to be easily integrated with capacitive and bridge 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. The ASIC also includes a high-accuracy integrated temperature sensor that enables the user to compensate for temperature dependencies of the sensor elements, as needed.
