Digital MEMS microphones integrate an analog-to-digital converter (ADC) inside the microphone capsule, providing direct digital output. This reduces external circuitry complexity, improves noise immunity, and enhances signal quality. They also enable advanced features such as programmable gain, filtering, and easier integration with digital signal processors (DSPs), making them ideal for modern smart devices.
Due to their digital output and integration capabilities, digital MEMS microphones are widely used in smartphones, tablets, laptops, smart speakers, hearing aids, and other IoT devices that require high-quality audio with minimal external processing.
