Digital Capacitive Plus Bridge Sensor Interfaces

Overview

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.

Key Features

  • Trimmable input capacitance range, for flexibility and dynamic
  • range optimization
  • Internally regulated bridge excitation voltage
  • Wide operating temperature range: -40 to 125°C
  • Extended operating supply voltage range: 1.71 to 3.6V
  • Internal high-accuracy and low-drift temperature sensor
  • On-chip processing engine for linearization and temperature
  • compensation – provides end-user with a fully calibrated output
  • Programmable resolution settings for each measurement mode:
  • 8, 10, 12, and 14-Bit for the temperature sensor and the capacitance interface
  • 14, 16, 18, and 20-Bit for the bridge sensor interface
  • Ultra-low sleep current: 25nA
  • Digital I2C and SPI interfaces

Applications

  • Pressure, Humidity, and
  • Temperature Monitoring
  • Home Automation Control
  • VAC / VAV
  • Pressure Transmitters
  • IoT Environmental Sensing
  • Level Sensing
