Top 10 Best Max9814

Add an ear to your project with this well-designed electret microphone amplifier. Built in automatic gain control. Great for when you want to record or detect audio in a setting where levels change. Can be easily used with any AnalogDigital converter that is up to 3.3V input.

The MAX9814 is a 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.br. The 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.br. A trilevel digital input programs the output amplifier gain. An external resistive divider controls the AGC threshold and a single capacitor programs the attackrelease times.br. 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.br. The MAX9814 is available in the space-saving, 14-pin TDFN package. This device is specified over the -40C to 85C extended temperature range. MAX9814 Simplified Block Diagram MAX9814 Simplified Block Diagram Enlarge.br.

The board comes with a 20-20KHz electret microphone soldered on. Using the MAX4466, an op-amp specifically designed for amplifier. For the best performance, use the quietest supply available on an for Arduino, this would be the 3.3V supply. The amplifier has excellent power supply noise rejection. This breakout board is best used for projects such as voice changers, audio recordingmpling, and audio-reactive projects that use FFT.

Application the MAX4466 microphone breakout is suitable for voice converters, audio recording and sampling, and audio response projects using FFT On the back, there is a small trimmer pot to adjust the gain You can set the gain from 25x to 125x. Parameters power supply voltage 2.4V to 5.5V can be compatible with STM, Raspberry Pi and other development board motherboards Power supply rejection ratio 112dB Common mode rejection ratio 126dB AVOL 125dB RL 100 thousands of ohm meter rail-to-rail output Quiescent power supply current less than 24 microamp Gain bandwidth 600kHz. 20-20KHz electret microphone soldered on comes with a 20-20KHz electret microphone soldered on the board for audio-reactive projects It is recommended to use the FFT driver library, which can take audio input and 'translate' it into frequencies. Easy to use connect GND to ground, VCC to 2.4-5VDC For the good performance, use the 'quietest' supply available this would be the 3.3V supply.
