Description

The AW89403 is a high performance, low power 4-channel audio analog-to-digital converter (ADC) for microphone array application. The device supports line and microphone inputs. The device integrates four PGAs for quad differential inputs, MIC1P & MIC1N, MIC2P & MIC 2N, MIC3P & MIC3N and MIC4P & MIC4N. The device supports simultaneous sampling of up to four analog channels or four digital channels for the pulse density modulation (PDM) microphone input. The device integrates programable channel gain, digital volume control, a programmable microphone bias voltage, a phase-locked loop (PLL), a programmable high-pass filter (HPF), low-latency filter mode, sum-mixer mode and allows for sample rates up to 768 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. AW89403 is available in a WBQFN 4X4-32L (Height 0.75) Package.
