2.12.1.3 Auxiliary Microphone Inputs (MIC1)
The MIC1 inputs are differential and do not include internal bias. To use these
inputs with an electret microphone, bias has to be generated outside the
WISMO Quik Q24x6 Series module according to the characteristic of this
electret microphone. These inputs are the standard ones used for an external
headset or a handsfree kit.
AC coupling is already embedded in the module.
2.12.1.3.1
Impedance of the microphone input in differential mode :
Differential connection
Module ON : R
in
= 10K
+/-10%
Module OFF : R
in
>1M
+/-10%
Typical implementation:
L1
L2
C1
C2
C4
C3
MIC1P
MIC1N
VCC
C5
R1
R2
R3
R4
Figure 4 : MIC1 inputs (differential connection)
R1 = R4 = from 100 to 330
R2 = R3 = usually between 1K
and 3.3K
as per the microphone
characteristics
C1 = 10pF to 33pF
C2 = C3 = C4 = 47pF to 100pF
C5 = 47μF
L1 = L2 = 100nH
R1 and R4 are used as a voltage supply filter with C5.
C1 has to be the nearest possible to the microphone. Microphone
manufacturers provide this capacitor directly soldered on the microphone.
C2 has to be very close to the WISMO Quik Q24x6 Series connector.
