AD74111YRUZ Datasheet PDF - ADI

●The AD74111YRUZ is a 2.5V Low Power 24-bit Sigma-Delta (Σ-Δ) Mono CODEC 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 >67dB THD+N and the DAC channel provides >88dB THD+N, both over an audio signal bandwidth. It 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 8kHz in the voice band range to 48kHz in the audio range.

● Supports 8kHz to 48kHz sample rates

● Programmable ADC gain

● On-chip volume control for DAC channel

● Software controllable clickless mute

● Master clock prescaler for use with DSP master clocks

● "Perfect Differential Linearity Restoration" for reduced idle tones and noise floor

● Data directed scrambling DAC - Least sensitive to jitter performance

●ESD sensitive device, take proper precaution while handling the device.
