In Home Theater and Entertainment designs such as AV receivers, soundbars, and smart speakers, an audio ADC is used to digitize audio from analog microphones or line inputs. The analog audio signal is converted to digital, where the signal can be processed by various immersive sound algorithms like surround sound, room correction, compression, reverberation, dynamic gain, and equalization. The processed audio can then be played back through speakers or headphones.
The PCM1822 is a Texas Instruments Burr-Brown™ high-performance, low-power, stereo-channel, simultaneous sampling, audio analog-to-digital converter (ADC) with flexible audio interface selectable with a hardware pin. The PCM1822 is designed for premium-quality audio applications.
