ICS-43434 Description

Short technical summary and product information.

The ICS-43434 from TDK InvenSense is a digital microphone featuring an industry-standard 24-bit I2S interface. This bottom-port microphone integrates a MEMS sensor, signal conditioning, an analog-to-digital converter, and filters into a compact 3.5 x 2.65 x 0.98 mm surface-mount package.

With a wide frequency response from 60 Hz to 20 kHz, a high Signal-to-Noise Ratio (SNR) of 65 dB, and an Acoustic Overload Point (AOP) of 120 dB SPL, the ICS-43434 is suitable for various audio applications. Its I2S interface allows direct connection to DSPs and microcontrollers, eliminating the need for an external audio codec.

The microphone is compatible with both Sn/Pb and Pb-free solder processes and is RoHS and WEEE compliant. Its small footprint and digital output make it ideal for integration into portable electronics, smart home devices, and wearables.

Note: This product is End of Life (EOL).
