ICS-40310

Ultra-low Current, Low-Noise Microphone with Analog Output

GENERAL DESCRIPTION

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.

*Protected by U.S. Patents 7,449,356; 7,825,484; 7,885,423; and 7,961,897.

Other patents are pending.
