Microphone Amplifier with Auto Gain Control Module

Product description:
MAX9814 - Microphone Amplifier with Auto Gain Control Module
This microphone amplifier module is a step above the rest, with built in automatic gain control. The AGC in the amplifier means that nearby 'loud' sounds will be quieted so they don't overwhelm & 'clip' the amplifier, and even quiet, far-away sounds will be amplified. This amplifier is great for when you want to record or detect audio in a setting where levels change and you don't want to have to tweak the amplifier gain all the time.- Automatic gain control (AGC)
- Three gain settings (40 dB, 50 dB, 60 dB)
- Programmable attack time
- Programmable attack and release ratio
- 2.7 V to 5.5 V supply voltage range
- Low input-referred noise density of 30 nV/√ Hz
- Low THD: 0.04% (typ)
- Low-power shutdown mode
- Built in 3.5mm audio jack
- On board Electret Mic
