Audio ADCs

An audio ADC is a type of analogue to digital converter that converts analogue sounds into digital signals using a mathematical function called quantisation. This conversion occurs periodically instead of continually to minimise noise generation. ADCs sample the input signals at specific points in time which reduces the allowable bandwidth of the input signal for increased efficiency.


What are audio ADCs used for?

ADCs are useful in dynamic range and dynamic specification applications. This is important in applications like vibration, seismic and geographical analysis. Other applications include microphones in radio, TV, electronic consumer and homeware devices. ADCs are also an important feature in telecommunication equipment, which requires analogue to digital conversion in order to produce good quality sound.


Types of audio ADCs

There are many types of audio ADCs. Choosing the right audio ADC depends on the number of channels your device has and the amount of analogue inputs and outputs required. You should also consider the required bit rates and the level of control/audio interface in engineering applications when choosing an Audio ADC.
