This device is also specified over the -40°C to +85°C extended temperature range. MAX9814 is a low-cost, high-quality microphone amplifier with automatic gain control (AGC) and low-noise microphone bias. The device features a low-noise preamplifier, variable gain amplifier (VGA), output amplifier, microphone-bias-voltage generator and AGC control circuitry.\u003c\/p\u003e\n\u003cp\u003eThe low-noise preamplifier has a fixed 12dB gain, while the VGA gain automatically adjusts from 20dB to 0dB, depending on the output voltage and the AGC threshold. The output amplifier offers selectable gains of 8dB, 18dB, and 28dB. With no compression, the cascade of the amplifiers results in an overall gain of 40dB, 50dB, or 60dB. A trilevel digital input programs the output amplifier gain. An external resistive divider controls the AGC threshold and a single capacitor program the attack\/release times. A trilevel digital input programs the ratio of attack-to-release time. The hold time of the AGC is fixed at 30ms. The low-noise microphone-bias-voltage generator can bias most electret microphones.\u003c\/p\u003e\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003col\u003e\n\u003cli\u003eBluetooth Headsets\u003c\/li\u003e\n\u003cli\u003eTwo-Way Communicators\u003c\/li\u003e\n\u003cli\u003eHigh-Quality Portable Recorders\u003c\/li\u003e\n\u003cli\u003eIP Phones\/Telephone Conferencing\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003col\u003e\n\u003cli\u003eSupply Voltage: 2.7v-5.5v @ 3mA current\u003c\/li\u003e\n\u003cli\u003eOutput: 2Vpp on 1.25V bias\u003c\/li\u003e\n\u003cli\u003eFrequency Response: 20Hz – 20 KHz\u003c\/li\u003e\n\u003cli\u003eProgrammable Attack and Release Ratio\u003c\/li\u003e\n\u003cli\u003eAutomatic gain, selectable max from 40dB, 50dB or 60dB\u003c\/li\u003e\n\u003cli\u003eLow Input-Referred Noise Density of 30nV\/\u003c\/li\u003e\n\u003cli\u003eLow THD: 0.04% (type)\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch2\u003eDocuments and Downloads\u003c\/h2\u003e\n\u003col\u003e\n\u003cli\u003eMAX9814 \u003ca href=\"https:\/\/datasheets.maximintegrated.com\/en\/ds\/MAX9814.pdf\"\u003eDatasheet\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003eMAX9814 \u003ca href=\"https:\/\/github.com\/alislahish\/Alislahish-MAX9814\"\u003eArduino Library\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch2\u003ePackage Includes\u003c\/h2\u003e\n\u003cp\u003e1 x MAX9814 Microphone Amplifier Module\u003c\/p\u003e\n\u003ch6\u003e\u003cspan style=\"color: #ffffff;\"\u003eAn internal link is any link from one page on your website to another page on your website.
