Description
- Application scenarios: cellular phones, repeating sound device, earphones, hearing aids, microphone preamplifiers, portable computers, voice recognition systems, etc. This fully assembled and tested board comes with a 20-20KHz electret microphone soldered on. Easy to use: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 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 = 100kΩ) rail-to-rail output; Quiescent power supply current: <24μA; Gain bandwidth: 600kHz Size:20.8MM*13.8MM*7.5MM This breakout board is best used for projects such as voice changers, audio recordingmpling, and audio-reactive or DIY projects that use FFT
