DESCRIPTION
●The TLV320AIC2x is a low-cost, low-power, highly-integrated, high-performance, dual-voice codec. It features two 16-bit analog-to-digital (A/D) channels and two 16-bit digital-to-analog (D/A) channels, which can be connected to a handset, headset, speaker, microphone, or a subscriber line via a programmable analog crosspoint.
●The TLV320AIC2x provides high resolution signal conversion from digital-to-analog (D/A) and from analog-to-digital (A/D) using oversampling sigma-delta technology with programmable sampling rate.
