25 Hz ~ 20 kHz Analog Microphone MEMS (Silicon) 1.5 V ~ 3.63 V Omnidirectional (-32dB @ 94dB SPL) Solder Pads
The ICS-40730 is a high-performance analog MEMS microphone designed for precision audio capture in compact electronic systems. It integrates a micro-electromechanical sensing element with an internal impedance conversion amplifier, providing a stable analog output suitable for direct interfacing with audio processing circuits. The device is optimized for applications requiring high signal integrity, low noise, and consistent performance across a wide frequency range. Its small form factor and surface-mount package make it ideal for space-constrained designs such as portable electronics, embedded systems, and industrial sensing equipment.
