Description
The AW89201 is a high performance, low power stereo channel audio analog-to-digital converter (ADC) for microphone array application.
The device supports line and microphone inputs. The device integrates two PGAs for stereo differential inputs, AINLP & AINLN, AINRP & AINRN. The device supports simultaneous sampling of up to two analog channels or two digital channels for the pulse density modulation (PDM) microphone input.
The device integrates programable channel gain, digital volume control, a programmable high-pass filter (HPF), and allows for sample rates up to 192 kHz.
The device supports time-division multiplexing (TDM), I2S, or left-justified (LJ) audio formats, and can be controlled with the I2C interface.
The device is very suitable for music and voice application, such as Microphone Array, Far field voice capture, Smart speaker, Conference system, Sound bar, Audio Interface, etc.
AW89201 is available in a WBQFN 3X3-20L (Height 0.55) Package.
