MAX4466 Sound Sensor Module Auto Gain Control AGC Amplifier Board for Live Broadcast Audio Signal Collection

Upgrade your audio projects with this high-performance MAX4466 Electret Microphone Amplifier Module, ideal for hobbyists and commercial developers alike! ### Core Advantages 1. Accurate Hi-Fi Sound Pickup: Featuring a top-tier electret condenser microphone core with a permanent electret diaphragm, it captures the full 20Hz-20kHz human-audible frequency spectrum precisely, converting sound pressure into stable electrical signals with minimal distortion to deliver high-quality audio data for follow-up signal processing. 2. Customizable Gain Adjustment: Built with the energy-efficient MAX4466 operational amplifier chip, it offers a 25x to 125x adjustable gain range with rail-to-rail output. Adjust the gain flexibly to match your use case, it supports both line-level audio input and microcontroller ADC sampling requirements completely free of signal clipping. 3. Robust Noise Resistance: Gold-plated contact PCB integrated with ferrite noise suppression components boasts a 112dB power rejection ratio and 126dB common mode rejection ratio, efficiently filtering out power supply ripples and environmental interference to ensure consistent, dependable signal output even in tough working conditions. 4. Broad Compatibility: Standard 3-pin (VCC, GND, OUT) header interface works with 2.4V-5.5V wide voltage input, is directly compatible with all 3.3V/5V development boards without requiring extra complex peripheral circuits, simplifying your project development process significantly. 5. Minimal Power Draw: Optimized low-power circuit design consumes only 24μA static operating current, greatly reducing power usage for battery-operated portable projects, prolonging battery runtime for long-duration audio monitoring or voice interaction applications. ### Product Specs Category: Electronic Sensor Module Component Materials: Electret Condenser Microphone, MAX4466 Amplifier Chip, Gold-Plated Printed Circuit Board, Metal Header Pins Size & Color: As shown in product images Use Scenarios: Voice recognition systems, sound triggered switches, decibel monitoring tools, audio recording sampling, music visualizer builds, IoT voice interaction devices Package Contents: 1 x Sensor Module + 1 x Set of 3-Pin Headers ### Reminders 1.
