Max9814 hookup

How to configure the max9814 with the breakout?

The chip at the heart of this amp is the MAX9814, and has a few options you can configure with the breakout. The default max gain is 60dB, but can be set to 40dB or 50dB by jumpering the Gain pin to VCC or ground. You can also change the Attack/Release ratio, from the default 1:4000 to 1:2000 or 1:500.

What is the overall gain of the max9814?

The overall gain of the microphone amplifier is selectable to 40dB, 50dB, or 60dB without compression. The MAX9814 incorporates compressor/limiter circuitry that limits the microphone output to a set voltage.

What is included in the max9814 IC?

The MAX9814 IC contains a low-noise amplifier, an output amplifier, a microphone bias-voltage generator, and automatic gain-control (AGC) internal circuitry. The overall gain of the microphone amplifier is selectable to 40dB, 50dB, or 60dB without compression.

What is a max9814 microphone?

The MAX9814 is a low-cost, high-quality microphone amplifier with automatic gain control (AGC) and a low-noise microphone bias. The MAX9814 consists of several distinct circuits: a low-noise preamplifier, a variable gain amplifier (VGA), an output amplifier, a microphone-bias-voltage generator, and AGC control circuitry.

What is the max gain on a max9814 AMP?

The chip at the heart of this amp is the MAX9814, and has a few options you can configure with the breakout. The default ‘max gain’ is 60dB, but can be set to 40dB or 50dB by jumpering the Gain pin to VCC or ground. You can also change the Attack/Release ratio, from the default 1:4000 to 1:2000 or 1:500.

Does the ak-max9814 breakout board require any programming?

The MAX9814 also has Automatic Gain Control (AGC) to avoid saturation when the board is placed close to the audio source. The AK-MAX9814 breakout board does not require any programming: it only requires a power supply between 2.7V - 5.5V.

What is the ak-max9814?

The Artekit AK-MAX9814 is a board with an electret microphone coupled to a high gain amplifier (the Maxim MAX9814) capable of gaining 40dB, 50dB and 60dB. The MAX9814 also has Automatic Gain Control (AGC) to avoid saturation when the board is placed close to the audio source.

What is the difference between the ak-max9814 and artekit ak-max9814?

The AK-MAX9814 is a board with a microphone and a high-gain amplifier with AGC. The Artekit AK-MAX9814 is a board with an electret microphone coupled to a high gain amplifier (the Maxim MAX9814) capable of gaining 40dB, 50dB and 60dB.

What is a max9814 amplifier used for?

This amplifier is great for when you want to record or detect audio in a setting where levels change and you dont want to have to tweak the amplifier gain all the time. The chip at the heart of this amp is the MAX9814, and has a few options you can configure with the breakout.

Is the max9814 active in production?

Active in Production. The 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.

How do I record music with the max9814 microphone?

press the tactile button to start the recording (the LED will light up to indicate this) The initial purpose of this project was to test the MAX9814 microphone, so I conducted three tests to find out the effect its inbuilt amplifier had on the result. While producing the recordings I used one of Mozart’s symphonys as a control variable.
