KAS-700-0149
Mics on Flex, 2 Pack, SPM0687LR5H-1,
WINFREY, Bottom Port Differential Analog
Knowles analog microphone exclusively for far field
IoT/ANC applications mounted on flexable bias boards
ASSEMBLY OVERVIEW
Bottom Port differential analog microphone mounted to flexible bias
board.
For use with Knowles “Muskie” Microphone Evaluation Kit.
Part# KAS-33100-0004
70dB Signal to Noise Ratio (SNR) enables far-field voice pick up for
IoT applications.
130dB Acoustic Overload Point (AOP) provides a large dynamic range
for barge-in applications.
Differential mode configuration improves noise immunity to power
supply variations, allowing extension of microphone PCB traces.
