    THEORY OF OPERATION
    The ADAU1381 is a low power audio codec with an integrated,
    fixed-function audio processing sound engine. It is an all-in-one
    package that offers high quality audio, low power, small size, and
    many advanced features. The stereo ADC and stereo DAC each
    have a dynamic range (DNR) performance of at least 96.5 dB and
    a total harmonic distortion plus noise (THD + N) performance
    of at least 90 dB. The serial data port is compatible with I2S, left-
    justified, right-justified, and TDM modes for interfacing to digital
    audio data. The operating voltage range is 1.8 V to 3.65 V, with
    an on-board regulator generating the internal digital supply voltage.
    The record path includes very flexible input configurations that
    can accept differential or single-ended analog microphone inputs
    as well as two stereo digital microphone inputs. There is also a
    beep input pin (BEEP) dedicated to analog beep signals that are
    common in digital still camera applications. A microphone bias
    pin that can power electrets-type microphones is also available.
    Each input signal has its own programmable gain amplifier (PGA)
    for input volume adjustment. An automatic level control (ALC)
    is built into the sound engine to maintain a constant input re-
    cording volume.
    The ADCs and DACs are high quality, 24-bit Σ-Δ converters
    that operate at selectable 64× or 128× oversampling rates. The
    base sampling rate of the converters is set by the input clock rate
    and can be further scaled with the converter control register
    settings. The converters can operate at sampling frequencies
    from 8 kHz to 96 kHz. The ADCs and DACs also include very
    fine-step digital volume controls.
    The playback path allows input signals and DAC outputs to be
    mixed into speaker and/or line outputs. The speaker driver is
    capable of driving 400 mW into an 8 Ω load.
    The fixed-function sound engine contains a digital audio
    processing flow optimized for digital still camera stereo audio
    processing. However, the flexibility offered by the built-in
    sound engine allows this codec to be used for a wide variety of
    low power applications. Signal processing blocks included in the
    sound engine include the following:
    Wind noise detection and autofiltering
    Dual-band compression with programmable crossover,
    compression curves, and timing
    Programmable multiband equalizer
    Configurable notch filter
    Enhanced stereo capture algorithm
    Automatic level control
    Digital volume control
    Multiplexers for signal routing
    The ADAU1381 can generate its internal clocks from a wide
    range of input clocks by using the on-board fractional PLL.
    The PLL accepts inputs from 11 MHz to 20 MHz.
    The ADAU1381 is provided in a small, 32-lead, 5 mm × 5 mm
    lead frame chip scale package (LFCSP) with an exposed bottom
    pad, or a 30-ball (6 × 5 bump), 3.4 mm × 2.64 mm wafer level
    chip scale package (WLCSP).
