ICS-40180

RF-Hardened, Low-Noise Microphone with Bottom Port and Analog Output

GENERAL DESCRIPTION

The ICS-40180

is an analog MEMS microphone with high SNR

and enhanced RF immunity. The ICS-40180 includes a MEMS

microphone element, an impedance converter, and an output

amplifier.

Other high-performance specification include a linear

response up to 124 dB SPL, tight ±1 dB sensitivity tolerance,

and enhanced immunity to both radiated and conducted RF

interference.

ICS-40180 APPLICATIONS INFORMATION CODEC CONNECTION The ICS-40180 output can be connected to a dedicated codec microphone input (see Figure 9) or to a high input impedance gain stage. A 0.1 µF ceramic capacitor placed close to the ICS-40180 supply pin is used for testing and is recommended to adequately decouple the microphone from noise on the power supply. A DC blocking capacitor is required at the output of the microphone.

ICS-40180 PCB DESIGN AND LAND PATTERN LAYOUT Below is the lay out the PCB land pattern for the ICS-40180, at a 1:1 ratio to the solder pads on the microphone package, (see Figure 11.) Take care to avoid applying solder paste to the sound hole in the PCB. Figure 12 shows a suggested solder-paste stencil pattern layout. The response of the ICS-40180 is not affected by the PCB hole size, as long as the hole is not smaller than the sound port of the microphone (0.25 mm, or 0.01 inch, in diameter). A 0.

ICS-40180 HANDLING INSTRUCTIONS PICK AND PLACE EQUIPMENT The MEMS microphone can be handled using standard pick-and-place and chip shooting equipment. Take care to avoid damage to the MEMS microphone structure as follows: • Use a standard pickup tool to handle the microphone. Because the microphone hole is on the bottom of the package, the pickup tool can make contact with any part of the lid surface.
