Pressure monitoring circuits and methods

摘要

In order to provide better resolution over a wider pressure range the previously available, the techniques disclosed herein set an output precision of an analog-to-digital converter (ADC) based on a control signal provided by a control element. The control signal sets the output precision of the ADC to a first level to measure an ambient pressure within a first pressure range; and signal sets the output precision of the ADC to a second level to measure an ambient pressure within a second pressure range.
