GENERAL DESCRIPTION
The ADAU1361 is a low power, stereo audio codec that supports
stereo 48 kHz record and playback at 14 mW from a 1.8 V analog
supply. The stereo audio ADCs and DACs support sample rates
from 8 kHz to 96 kHz as well as 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 inputs. The inputs can be mixed and muxed before the
ADC, or they can be configured to bypass the ADC. The
ADAU1361 includes a stereo digital microphone input.
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 analog outputs. The output mixer
stage allows for flexible routing of audio.
The serial control bus supports the I
serial audio bus is programmable for I
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.
