SPK0415HM4H-B
Digital High-SNR SiSonic^TM Microphone
The SPK0415HM4H-B is a miniature, high-
performance, low power, top port silicon
digital microphone with a single bit PDM
output. Using Knowles’ proven high
performance SiSonic^TM MEMS technology,
the SPK0415HM4H-B 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 audio performance
and RF immunity are required. The high
Signal-to-Noise-Ratio (SNR) of the
SPK0415HM4H-B enhances the performance
of far-field applications and many complex,
multi-microphone algorithms.
