Knowles sensors spk0641lm4h-1-t digital microphone

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. These devices are suitable for applications such as cellphones, smart phones, laptop
computers, sensors, digital still cameras, portable music recorders, and other portable electronic
devices where excellent wideband audio performance and RF immunity are required. 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.
