24-bit Cap-less ADC 106 dB SNR with ASRC 6 channels
Overview
The hexADC-uLP-SW1.01 is a mixed (analog and digital) Virtual Component containing six mono ADCs, and additional functions offering an ideal mixed signal front-end for low power, fast wake-up and high quality audio applications. It features ASRC and two different audio streams to ensure multi-sources compatibility and high performance smartspeaker applications.
Key Features
- I2C and APB control interface
- Embedded low noise voltage regulator for best resilience to power supply noise
- Low BoM and capacitor-less input connection
- High dynamic range for high quality recording in far-field applications
- Fast wake-up suitable for the unique analog VAD WhisperTrigger-A
- Ultra low power mode, ideal for battery powered voice first devices
