Figure 14: Example of MIC1 input differential connection without LC filter
*:Z1 is from 200Hz to 4kHz. For more characteristics refer to the chapter 3.11.1.1.1.
The capacitor C1 is highly recommended to eliminate the TDMA noise. C1 must be
close to the microphone.
Recommended components:
• C1 : 12pF to 33pF (needs to be tuned depending on the design)
• C2, C3, C4 : 47pF (need to be tuned depending on the design)
• L1, L2 : 100nH (need to be tuned depending on the design)
