        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
