Non-inverting microphone pre-amplifier circuit
CIRCUIT060016
Overview
This circuit uses a non–inverting amplifier circuit configuration to amplify the microphone output signal. This circuit has very good magnitude flatness and exhibits minor frequency response deviations over the audio frequency range. The circuit is designed to be operated from a single 5-V supply.
Features
- Single 5-V supply
- Input pressure: 100 dB SPL (2 Pa)
- Max output: 1.228 Vrms
- Frequency range: 20 Hz to 20 kHz
