ICS-40618 High Dynamic Range Microphone

InvenSense presents a high dynamic range microphone with differential output and low power

Image of InvenSense ICS-40618 High Dynamic Range MicrophoneInvenSense's ICS-40618 is a bottom port microphone with a differential analog output. This microphone can capture a very wide dynamic range with very low power consumption. The ICS-40618 integrates a MEMS transducer, and differential output amplifier in a small 3.50 mm x 2.65 mm x 0.98 mm bottom port package.

The ICS-40618 enables high performance acoustic applications with a very high 67 dB SNR and a 132 dB SPL AOP. Its low power consumption makes this microphone a good choice for IoT, mobile, and industrial applications.
