ICS-40310Ultra Low Current, Low-Noise Microphone with Analog OutputNote: The ICS-40212 is the recommended replacement for ICS-40310. The ICS-40310 is a high-performance MEMS microphone with a combination of very low power consumption, high SNR, and a tiny package. Running from a 1 V supply, the ICS-40310 consumes only 16 μA of current while providing a 64 dB SNR with an analog 4.5 kΩ impedance output. These features, combined with the benefits of MEMS technology, reflow solder compatibility, and a highly stable response over time and temperature, make the ICS-40310 an ideal microphone choice for always-on power-sensitive mobile devices. The ICS-40310 is pin-compatible with the INMP504 and INMP510. |
