CMT3501B2

The CMT3501B2 is an ideal single-chip solution for high precision signal measurement with an I²C interface to provide accurate Temperature, Pressure or Altitude data.

Description

The CMT3501B2 is an ideal single-chip solution for high precision signal measurement with an I²C interface to provide accurate Temperature, Pressure or Altitude data. The device digitizes the incoming Pressure and Temperature signals by an internal high resolution 24-bit ADC. The Altitude value is calculated by a specific patented algorithm according to the pressure and temperature data. Data compensation is integrated internally to save the effort of the external host MCU system. Easy command-based data acquisition interface and programmable interrupt control is available.
