Product description
MEMS microphone with digital I²S output. TDK InvenSense ICS-43434 is a digital, bottom-ported microphone with I²S output. 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 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 multiple operating modes: High Performance, Low Power (AlwaysOn), and Sleep. The ICS-43434 features high SNR and an AOP of 120 dB SPL in all operating modes. The microphone has a high signal-to-noise ratio of 64 dBA and a wideband frequency response. The sensitivity tolerance of the ICS-43434 is ±1 dB, enabling high-performance microphone arrays without the need for system calibration.
The ICS-43434 is available in a small surface-mount package with dimensions of 3.50 × 2.65 × 0.98 mm. The ICS-43434 is function-compatible with the ICS-43432 and provides equivalent electro-acoustic performance at lower power consumption and in a smaller package.
Applications:
- Wearable electronics
