Ferwooh 3PCS MAX9814 Electret Microphone Auto Gain Control Amplifier Sensor Module AGC Amplifier Board VGA Low Noise
Asin: B0D1FY21YH
Features
- The Max9814 is a high -quality microphone amplifier with automatic reinforcement control and noise -hable microphone preload. The device has a low-noise preamplifier, an amplifier with a variable reinforcement, an output amplifier, a microphone preload generator and an automatic gain control group.
- The noise-shaped preamplifier has a firm reinforcement of 12 dB, while the VGA reinforcement is automatically adjusted from 20 dB to 0 dB depending on the output voltage and AGC threshold. The output amplifier offers selectable reinforcements of 8 dB, 18 dB and 28 dB. Without compression, the cascading of the amplifiers leads to a total reinforcement of 40 dB, 50 dB or 60 dB.
- A three -stage digital entrance programs the strengthening of the output amplifier. An external resistance divider controls the automatic gain control threshold and a single capacitor programs the Attack/Release times.
- A three-stage digital entrance programs the ratio of Attack to release time. The AGC timeout is set to 30 ms. The noise microphone preload generator can tense the most electret microphones.
- The Max9814 is available in the space-saving 14-pin TDFN housing. This device is specified for an extended temperature range from -40 C to +85 C; 2.7 V to 5.5 V supply voltage area; only 0.04 % (typical) THD; Deputy mode with low power consumption; Built -in 2V low noise microphone bias.
