SPK0833LM4H-B
Digital Zero-Height SiSonic^TM Microphone
The SPK0833LM4H-B is a miniature, high-
performance, low power, bottom port
silicon digital microphone with a single bit
PDM output. Using Knowles’ proven high
performance SiSonic^TM MEMS technology,
the SPK0833LM4H-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 wideband audio
performance and RF immunity are required.
