... Notes on Application Take care of the followings because the CXA3067M has limiter voltage gain of approximately 67 dB and uses high frequency. 1) Separate the input pattern from the output pattern as far as possible and makes wiring short. 2) Ground the decoupling capacitor as close to pin 13 as possible. ...
