Description

This is Mono Audio Codec.

The 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 >67 dB THD+N and the DAC channel provides >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. An on-chip reference voltage is included but can be powered down and bypassed by an external reference source if required. The AD74111 offers sampling rates that, depending on MCLK selection and MCLK divider ratio, range from 8 kHz in the voiceband range to 48 kHz in the audio range. The AD74111 is available in a 16-lead TSSOP package option and is specified for the automotive temperature range of –40°C to +105°C.
