SPH1642HT5H-1
Wide Bandwidth, Low Noise, Precision
Top Port SiSonic™ Microphone
SPH1642HT5H-1
Rev B Datasheet
The SPH1642HT5H-1 is a miniature, highꢀperformance, low power, top port silicon microphone.
Using Knowles’ proven high performance SiSonic™ MEMS technology, the SPH1642HT5H-1 consists
of an acoustic sensor, a low noise input buffer, and an output ampliꢁier. 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.

Maximum of 3 reꢁlow cycles is recommended.
In order to minimize device damage:
• Do not board wash or clean after the reꢁlow process.
• Do not brush board with or without solvents after the reꢁlow 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.
