ICS-40310
Ultra-low Current, Low-Noise Microphone with Analog Output
GENERAL DESCRIPTION APPLICATIONS
The ICS-40310* is a high-performance MEMS microphone Dedicated AlwaysOn Microphone
with a combination of very low power consumption, high SNR, Smartphones
Wearable Computing Devices
and a tiny package. Running from a 1 V supply, the ICS-40310
Tablet Computers
consumes only 16 A of current while providing a 64 dB SNR
Bluetooth Headsets
with an analog 4.5 k impedance output. These features,
combined with the benefits of MEMS technology, reflow
solder compatibility, and a highly stable response over time
FEATURES
and temperature, make the ICS-40310 an ideal microphone
Low Current Consumption: 16 A
choice for always-on power-sensitive mobile devices.
Small Surface-Mount Package: 3.35 2.5 0.98 mm
The ICS-40310 is pin-compatible with the INMP504 and
High SNR of 64 dBA
INMP510.
Sensitivity of 37 dBV
0.9 V to 1.3 V Supply
