Descriptions:
MAX9814 electret microphones amplified board with the function of AGC, can be directly driven the headset (if the voice is not big enough, can add a zoom), applicable to meeting microphone, propaganda, bluetooth headset, computer microphones, etc.
short-circuit cap is used to set the release ratio, gain, AGC, (BIAS - TH is setting AGC switch function, the two terminal open circuit state are AGC function,use short circuit cap connect AGC switch ).
Gain and release than Settings:
A/R :
three start-up and release than choice, control of the AGC circuit start time and release time than:
A/R = GND: start/release ratio of 1:500
A/R = VDD: start/release ratio of 1:2000
A/R = dangling: start/release than 1:4000
GAIN:
three states amplifier GAIN control:
GAIN = VDD, GAIN is set to 40 db
GAIN = GND, GAIN is set to 50 db
Gain = dangling, no compression Gain is set to 60 db
Note:
it is 4.3 v to 12 v power supply from 4.3 v to 12 v power supply Port input
Sent Power lines 200 mm (length) and output line length (300 mm)
