Design of a Digital Audio Module for Ultra-Low Power Cellular Applications
Cellular audio applications depend on an audio interface to connect a microphone/speaker. Acoustic waves, usually voice, are captured by a microphone, amplified and subsequently sampled into the digital domain by an Analog to Digital Converter (ADC). In the other direction a stream of digital audio samples is first mapped into the analog domain by and Digital to Analog Converter (DAC) and subsequently amplified to drive a speaker, where the analog signal is translated into acoustic waves.
A huge variety of integrated audio modules such as  exist on the marked. In cellular application an audio chip can be placed between microphone/speaker and a cellular modem. However, emerging applications, such as emergency watches  or ambulance drones , require highly integrated components due to their low footprint and extremely low power consumption.
