Microphones Procurement Notes

Verify the specific ordering suffix to confirm packaging configuration, as the component is available in Tape & Reel, Cut Tape, and Digi-Reel formats. Ensure the selected variant matches the required quantity per reel or cut tape specifications for your assembly process. Confirm that the analog output characteristics align with your system's input impedance requirements.

Microphones Selection Notes

Select this component when an analog output is required rather than digital PDM or I2S interfaces. The -38 dB sensitivity and 66 dB SNR provide adequate performance for general voice pickup applications. Consider the 190 µA supply current for power budgeting in always-on or battery-powered designs. The small footprint allows integration into space-constrained consumer products.

Microphones Part Context

The ICS-40212 belongs to TDK InvenSense’s portfolio of MEMS microphones, which includes various analog and digital options. This model represents the analog segment, contrasting with digital variants like the INMP series. It is designed for cost-sensitive applications where simple analog front-end circuitry is preferred over complex digital interfaces.
