芯奧微硅麥


1. GENERAL DESCRIPTION
is a Silicon Microphone with analog output and top inlet for
sound input. It is a cost-effective alternative to traditional electret condenser
microphone (ECM). Provided on tap-and-reel, it is ideally suited for high volume
applications. And it can be processed directly to customer’s PCB using standard
automatic pick-and-place equipment and surface mounted via standard solder reflow
equipment.
can be used in (but not limited to) the following applications:
1. Portable communication device
2. Notebook and desktop
3. Headphone and headset accessories
4. Smart Remote Control



2. ABSOLUTE MAXIMUM RATINGS
Supply voltage: VDD to GND…………-0.3V~5V
ESD Tolerance
The Lid Mode ……………………………8kV
The I/O Pin Mode ……………………….4kV


3. ACOUSTIC & ELECTRICAL SPECIFICATIONS
Unless otherwise specified, test conditions are:
Typical specification are measured at VDD = 3.0V
Input sound pressure PIN = 94dB SPL@1kHZ
Test room temperature Ta = 25℃,Room Humidity = 50±20%
SNR & noise floor measurement is based on 20 – 20 KHz pass band with A-Weighting
