INMP510
RF-Hardened, Ultra-Low Noise Microphone with Bottom Port and Analog Output
GENERAL DESCRIPTION
The INMP510* is an RF-hardened, analog output, bottom-ported,
omnidirectional MEMS microphone with high performance,
ultra-low noise, and low power. The INMP510 consists of a
MEMS microphone element, an impedance converter, and an
output amplifier. The INMP510 sensitivity specification makes
it an excellent choice for both near-field and far-field
applications. The INMP510 is pin compatible with the INMP504
microphone. The INMP510 has a very high signal-to-noise
ratio (SNR) and extended wideband frequency response,
resulting in natural sound with high intelligibility. Low current
consumption enables long battery life for portable
applications.
The INMP510 is available in a miniature 3.35 × 2.5 × 0.98 mm
surface-mount package. It is reflow solder compatible with no
sensitivity degradation.
*Protected by U.S. Patents 7,449,356; 7,825,484; 7,885,423; and 7,961,897.
Other patents are pending.

APPLICATIONS INFORMATION
CONNECTING TO AUDIO CODECS
The output of the INMP510 can be connected to a dedicated codec microphone input (see Figure 9) or to a high input impedance
gain stage (see Figure 10). A 0.1 µF ceramic capacitor placed close to the INMP510 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. This capacitor creates a high-pass filter with a corner frequency at
fC = 1/(2π × C × R)
where R is the input impedance of the codec.
A minimum value of 2.2 μF is recommended in Figure 9 because the input impedance of codecs can be as low as 2 kΩ at their
highest PGA gain setting, which results in a high-pass filter corner frequency at 37 Hz. Figure 10 shows the INMP510 connected to an
op amp configured as a noninverting preamplifier.

PCB DESIGN AND LAND PATTERN LAYOUT
The recommended PCB land pattern for the INMP504 should be laid out to a 1:1 ratio to the solder pads on the microphone
package, as shown in Figure 8. Take care to avoid applying solder paste to the sound hole in the PCB. A suggested solder paste
stencil pattern layout is shown in Figure 9. The diameter of the sound hole in the PCB should be larger than the diameter of the
sound port of the microphone. A minimum diameter of 0.5 mm is recommended.

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.
Do not pick up the microphone with a vacuum tool that makes contact with the bottom side of the microphone.
Do not pull air out of or blow air into the microphone port.
Do not use excessive force to place the microphone on the PCB.
REFLOW SOLDER
For best results, the soldering profile must be in accordance with the recommendations of the manufacturer of the solder paste used to
attach the MEMS microphone to the PCB. It is recommended that the solder reflow profile not exceed the limit conditions specified in
Figure 1 and Table 3.
BOARD WASH
When washing the PCB, ensure that water does not make contact with the microphone port. Do not use blow-off procedures or
ultrasonic cleaning.
