ICS-43434

The ICS‐43434 is digital I2S output bottom port microphone. The complete ICS‐43434 solution consists of a MEMS sensor,signal conditioning, an analog‐to‐digital converter, decimation and antialiasing filters, power management, and an industry standard 24‐bit I²S interface. The I²S interface allowsthe ICS‐43434 to connect directly to digital processors,such as DSPs and microcontrollers, without the need for an audio codec in the system. The ICS‐43434 has multiple modes of operation: High Performance, Low Power (AlwaysOn) and Sleep. The ICS‐ 43434 has high SNR and 120 dB SPL AOP in all operational modes.
