ICS-40619

音频控制器, MEMS 麦克风, 1.5V 至 2V, LGA, 6 引脚, -40 °C

High SNR Microphone with Differential Output and Low -Power Mode The TDK Invensense is an analog MEMS microphone with very high SNR and a low-power AlwaysOn mode. The ICS-40619 includes a MEMS microphone element, an impedance converter, and a differential output amplifier. This microphone features a low-power mode, which is activated when the supply voltage is <2.0 V. In this mode, the ICS-40619 operates with 55 µA. Other high-performance specifications include 132 dB SPL acoustic overload point in high performance mode, tight ±1 dB sensitivity tolerance and enhanced immunity to both radiated and conducted RF interference. The ICS-40619’s electro-acoustic performance matches the bottom port ICS-40618, making this pair of microphones suitable to use together in applications requiring both top and bottom port devices. The ICS-40619 is available in a small 3.50 mm × 2.65 mm × 0.98 mm top port surface-mount package.
