The TLV320AIC33, TLV320AIC3106 and TLV320AIC34 high- performance, low-power stereo audio codecs are the industry’s only I2S codecs capable of interfacing directly to digital or analog microphones. These codecs, which are ideal for portable applications like smartphones, personal digital assistants (PDAs), voice/audio processors, conferencing IP phones and other portable audio equipment, accept either a digital bit stream from a digital microphone or the typical differential or single-ended inputs from traditional analog microphones.
