Overview
The TLV320AIC24KIPFB is a low-power, highly-integrated, high-performance dual-voice codec produced by Texas Instruments. This component is part of the TLV320AIC2x family and is designed for various voice-band applications. It features two 16-bit analog-to-digital (A/D) channels and two 16-bit digital-to-analog (D/A) channels, utilizing oversampling sigma-delta technology for high-resolution signal conversion. The codec is highly versatile, supporting connections to handsets, headsets, speakers, microphones, and subscriber lines via a programmable analog crosspoint.
