The ICS-43434 is a digital I2S output bottom port microphone. The ICS-43434 provides a direct Audio to Digital solution in which no Codec is needed to get direct sampled audio straight to a MCU/DSP/FPGA/etc. It follows the industry standard 24-bit I2S interface for easy connection to any MCU/SOC that has an I2S interface. It provides 3 operation modes: High Performance(~490uA), Low Power(230uA) and Sleep(~12uA) with 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. The smMIC-ICS43434 provides an ultra-small form factor evaluation board for the ICS-43434 to easily incorporate into prototypes and wire into MCU/SOC evaluation kits. Or even solder directly into a prototype system.

Sensor Maestros has developed Firmware drivers for the ICS-43434 on several MCU/SOC platforms such as Nordic, NXP/Kinetis, ST, etc. Submit inquiry for further information.
