ICS-43434 Multi-Mode Microphone

TDK InvenSense ICS-43434 is a digital I²S output bottom port microphone with multiple modes of operation. The complete ICS-43434 solution consists of a MEMS sensor, signal conditioning, an analog-to-digital converter, decimation and antialiasing filters, power management, and a 24-bit I²S interface. The I²S interface allows the 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 High Performance, Low Power (AlwaysOn), and Sleep mode operations. The ICS-43434 has high SNR and 120dB SPL AOP in all operational modes. The microphone has a high SNR of 65dBA and a wideband frequency response. With a sensitivity tolerance of ±1dB, the ICS-43434 enables high-performance microphone arrays without the need for system calibration. The ICS-43434 is available in a small 3.50mm × 2.65mm × 0.98mm surface mount package with an operating temperature of -40°C to +85°C. The ICS-43434 is function compatible with the ICS-43432 while providing equivalent electro-acoustic performance at lower power consumption and in a smaller package.
