This circuit is used to interface an analog MEMS microphone to a microphone preamplifier, as shown in Figure 1. The ADMP504 consists of a MEMS microphone element and an output amplifier. Analog Devices\' MEMS microphones have a high signal-to-noise ratio (SNR) and a flat, wideband frequency response, making them an excellent choice for high-performance, low-power applications.
