AD74111YRUZ

AD74111 is a front-end processor for general-purpose audio and voice applications. It features a multibit - A/D conversion channel and a multibit - D/A conversion channel. The ADC channel provides <gt/>67 dB THD+N and the DAC channel provides <gt/>88 dB THD+N, both over an audio signal bandwidth. The AD74111 is particularly suitable for a variety of applications where mono input and output channels are required, including audio sections of digital video camcorders, portable personal audio devices, and telematic applications. Its high quality performance also makes it suitable for speech and telephony applications such as speech recognition and synthesis, and modern feature phones. Application includes digital video camcorders (DVC), portable audio devices (Walkman®, PDAs, and so on), audio processing, voice processing, telematic systems, general-purpose analogue I/O.
