SPW2430HR5H-B
Top Port SiSonicTM Microphone The SPW2430HR5H-B is a miniature, highperformance, low power, top port silicon
microphone. Using Knowles’ proven high
performance SiSonicTM MEMS technology,
the SPW2430HR5H-B consists of an acoustic
sensor, a low noise input buffer, and an
output amplifier. These devices are suitable
for applications such as cellphones, smart
phones, laptop computers, sensors, digital
still cameras, portable music recorders, and
other portable electronic devices where
excellent audio performance and RF
immunity are required. Revision:B

1. ABSOLUTE MAXIMUM RATINGS
Parameter Absolute Maximum Rating Units VDD to Ground -0.5, +5.0 V OUT to Ground -0.3, VDD + 0.3 V ±5 mA Storage Temperature -40 to +100 °C Operating Temperature -40 to +100 °C Input Current to Any Pin Stresses exceeding these “Absolute Maximum Ratings” may cause permanent damage to the device. These are
stress ratings only. Functional operation at these or any other conditions beyond those indicated under “Acoustic
& Electrical Specifications” is not implied. Exposure beyond those indicated under “Acoustic & Electrical
Specifications” for extended periods may affect device reliability. 2. ACOUSTIC & ELECTRICAL SPECIFICATIONS TEST CONDITIONS: 23 ±2°C, 55±20% R.H., VDD(min) < VDD < VDD(max), no load, unless otherwise indicated
