Rail-To-Rail Electret Mic Amplifier

Pre-assembled electret microphone amplifier board built around the Maxim MAX4466 op-amp and a 20–20 kHz electret element. Dimensions: 22 × 15 × 8 mm; weight ~2 g; FR-4 substrate. Gain adjustable from 25× to 125× using onboard trimmer pot. Rail-to-rail output with VCC/2 DC bias provides ~200 mVpp at standard speech volume (6″), scalable to ~1 Vpp for microcontroller ADC use or up to 5 Vpp at full swing. Operates on 2.4–5 VDC; 3.3 V supply yields lowest noise floor. Output is not load-driving — intended for ADCs, FFT processors, or audio interface inputs. AC coupling with 100 µF capacitor optional if downstream device requires true AC-coupled input.
