Features:
1 .This paragraph baby voice acquisition boards, voice amplifier module, a microphone module, pickup module, microphone and audio capture module.
2, Function: and after amplification by microphone output sound signal acquisition, amplification 20dB fixed gain. They have a small size, built-in low-noise microphone bias. The amplifier gain-bandwidth product of 500kHz, output up to full swing, with the industry's top level of 100dB PSRR, low THD+N (0.015%). Also it has a series of energy-saving features: only 230pA of supply current, overall shutdown mode the supply current drops and the sum of the bias current 100nA.
3, The standard two-panel design, machine patch.
4, Interface specification,+5V-24V and GND are connected to the power supply and ground, OUT outputs the amplified voice signal.
5, Single-supply, voltage DC: 5V-24V
6, Board size: 16.4 (mm) x9.7 (mm)
7, The output of the speech acquisition board OUT side contect voice band-pass filter can effectively remove all kinds of noise, make effect better.

Package Included:
1x MAX9812 Electret Microphone Receiver Amplified Board
