SPK0415HM4H-B
Digital High-SNR SiSonicTM 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 SiSonicTM 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.
Features:
• Low Noise
• Low Current
• RF Shielded
• PDM Output
• Supports Dual Multiplexed Channels
• Ultra-Stable Performance
• Standard SMD Reflow
• Omnidirectional

12. ADDITIONAL NOTES
(A) MSL (moisture sensitivity level) Class 1.
(B) Maximum of 3 reflow cycles is recommended.
(C) In order to minimize device damage:
• Do not board wash or clean after the reflow process.
• Do not brush board with or without solvents after the reflow process.
• Do not directly expose to ultrasonic processing, welding, or cleaning.
• Do not insert any object in port hole of device at any time.
• Do not apply over 30 psi of air pressure into the port hole.
• Do not pull a vacuum over port hole of the microphone.
• Do not apply a vacuum when repacking into sealed bags at a rate faster than 0.5 atm/sec.
