μ
PC8130TA,
μ
PC8131TA
APPLICATION EXPLANATION
The
μ
PC8130TA and
μ
PC8131TA has difference in internal circuit in order to reduce the number of external
component with
μ
PC8119T and
μ
PC8120T. For this reason, they have difference in mechanism for determing
minimum gain and external suitable constant.
Determing Minimum Gain
External Feedback Capacitor of
V
CC
to V
AGC
Pin
Optimize Choke Inductance of
π
Type Circuit on V
CC
Line
μ
PC8119T
μ
PC8120T
High frequency negative feed back
between OUT, V
CC
and V
AGC
pin
optimized by external choke
inductance.
Necessary
The impedance of inductance
should be very low at high
frequency region.
