The ICS-43434 is a digital I2S output microphone featuring a bottom sound port.  The ICS-43434 provides a direct Audio to Digital solution.  No Audio Codec is needed to get direct sampled audio straight to a host processor.  The ICS-43434 follows the industry standard 24-bit I2S interface for easy connection to any host processor that has an I2S interface. It provides 3 operation modes: High Performance(~490uA), Low Power(230uA) and Sleep(~12uA) while being powered from a 1.8V source. In a very small package size of 3.5×2.65×0.98mm it also provides a high SNR of 64dBA across a 20KHz bandwidth along with an exceptional Dynamic Range of 90dB.
