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.
