5 Applications Information
Cirrus Logic provides a range of audio codecs incorporating an analog microphone input interface. These codecs support
direct connections to silicon microphones such as the CS7331P.
Further information on Cirrus Logic audio codecs is provided in the respective product data sheet, which is available from
the Cirrus Logic website.
5.1 Important Assembly Guidelines
• Do not put a vacuum over the port hole of the microphone. Placing a vacuum over the port hole can damage the
device.
• Do not board wash the microphone after a reflow process. Board washing and the associated cleaning agents can
damage the device.
• Do not expose to ultrasonic cleaning methods.
• Do not use a vapor phase reflow process. The vapor can damage the device.
• Please refer to application note WAN0273 MEMS Mic Assembly and Handling Guidelines for further assembly and
handling guidelines.
