SPH0641LU4H-1
Digital Zero-Height SiSonicTM Microphone
With Multi-Mode And Ultrasonic Support
The SPH0641LU4H-1 is a miniature, high-
performance, low power, bottom port
silicon digital microphone with a single bit
PDM output. Using Knowles’ proven high
performance SiSonicTM MEMS technology,
the SPH0641LU4H-1 consists of an acoustic
sensor, a low noise input buffer, and a
sigma-delta modulator. This microphone is
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.
In addition, the SPH0641LU4H-1 offers
multiple performance modes and supports
ultrasonic applications.
Features:
High SNR of 64dB
Low Current Consumption of 235uA in
Low-Power Mode
Multiple performance modes (Sleep,
Low-Power, Standard Performance and
Ultrasonic Modes)
Flat Frequency Response
RF Shielded
Zero-Height MicTM
Supports Dual Multiplexed Channels
Standard SMD Reflow
Omnidirectional
Ultrasonic Support
