Abstract
A MEMS microphone integrates a temperature-sensing element in or on the ASIC die of a MEMS microphone to enable an audio mode and a temperature-sensing mode in parallel. The system also permits for a method for easily switching between these two modes and for outputting both digital output signals at the same common output pad, which allows for the use of the footprint of a conventional microphone.
