1. Control input circuit
TA8423P/F
VRF (= RF·IL) of feed back voltage is feed backed to negative input of control amp internally.
Voltage gain becomes approximately equal to 1 (0dB) by this internal feed back.
Note:
2 terminals (Pin (3), (13) for F version and Pin (3), (14) for P version) are provided for RF terminal to
decrease the interference caused by internal common impedance.
Both Pins are required to connect for stable operation.
