PRODUCTION DATA.
Electret microphones are commonly used in portable electronics because of their small size, low cost, and relatively good signal-to-noise ratio (SNR). The small package size and excellent AC performance of the OPA364 make it an excellent choice for preamplifier circuits for electret microphones. The circuit shown in Figure 31 is a single-supply preamplifier circuit for electret microphones.
