Sobre este producto
- MAX4466 Electret Microphone Amplifier Module – Adjustable Gain Preamp for Arduino/ADC Signal Conditioning Key Features 25x–125x Adjustable Gain – On-board trimmer potentiometer for precise sensitivity tuning (200mVpp–1Vpp output range). Rail-to-Rail Output – 0–5Vpp swing capability with VCC/2 DC bias, ideal for direct ADC sampling (3.3V/5V microcontrollers). 2.4–5V DC Operation – Low quiescent current (1.2mA) for battery-powered voice-activated or audio-reactive projects. AC/DC Coupling Flexibility – Optional 100μF output capacitor for AC-coupled audio amplifiers or line-level inputs. Compact Design – Breadboard-friendly breakout board with labeled GND, VCC, and OUT pins for rapid prototyping. Applications Sound threshold detection in IoT devices. FFT-based frequency analysis for interactive installations. Pre-amplification for low-sensitivity microphones in PA systems. Package Includes 4 x MAX4466 amplifier modules.
