The SPK0641HT4H-1 is a miniature, high-performance, low power, top port silicon digital microphone with a single-bit PDM output.
Using Knowles’ proven high performance SiSonicTM MEMS technology, the SPK0641HT4H-1 consists of an acoustic sensor, a low noise input buffer, and a sigma-delta modulator.
The high Signal-to-Noise Ratio (SNR) of the SPK0641HT4H-1 enhances the performance of far-field applications and many complex, multi-microphone algorithms. In addition, the SPK0641HT4H-1 offers multiple performance modes.
