Overview
The TLV320AIC24KIPFBR is a low-cost, low-power, highly-integrated, high-performance dual-voice codec produced by Texas Instruments. This component 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 various devices such as handsets, headsets, speakers, microphones, or subscriber lines via a programmable analog crosspoint. It utilizes oversampling sigma-delta technology for high-resolution signal conversion and supports a range of programmable sampling rates.
