Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The PCM3140QRGERQ1 is an automotive-grade four-channel, 768kHz Burr-Brown™ audio analog-to-digital converter (ADC) with 106dB SNR. This audio ADC supports line and microphone inputs, allowing for both single-ended and differential input configurations. The PCM3140QRGERQ1 also supports simultaneous sampling of up to four analog channels or eight digital channels for pulse density modulation (PDM) microphone inputs. These high-performance audio ADCs can be powered by a single supply of 3.3V or 1.8V. This makes the device an excellent choice for audio systems with limited space in far-field microphone recording applications. The PCM3140QRGERQ1 device meets the requirements of automotive applications.
