EVAL-ADAU1361Z: Stereo, Low Power, 96 kHz, 24-Bit Audio Codec with Integrated PLL
The ADAU1361 is a low power, stereo audio codec supporting stereo 48 kHz record and playback at 10 mW from a 1.8 V analog supply. The stereo audio ADCs and DACs support sampling rates from 8 kHz to 96 kHz and a digital volume control. The ADAU1361 is ideal for battery-powered audio and telephony applications.
The record path includes an integrated microphone bias circuit and six input paths. The multiple inputs can be mixed and muxed before the ADC. In addition, it is possible to route the analog inputs around the mixed signal section directly to the output analog mixers. A stereo digital microphone input is also supported.
The ADAU1361 includes five high power output drivers (two differential and three single-ended), supporting stereo head-phones, an earpiece, or other output transducer. AC-coupled or capless configurations are supported. Individual fine level controls are supported on all seven output pins. The output mixer stage allows for flexible routing of audio.
The serial control bus supports the I²C and SPI protocols. The serial audio bus is programmable for I2S, left-/right-justified, and TDM modes. A programmable PLL supports flexible clock generation for all standard integer rates and fractional master clocks from 8 MHz to 27 MHz.
