Application Note
1. AM low-cut circuit
The AM Low-Cut action is carried out by the bypass of the high frequency
component of the positive-feedback signal at the AF AMP stage.
The external capacitor: C3 by-passes this component.
The cut-off frequency fL is determined by the internal resistance 10 k
(typ.) and the external capacitor C3 as following ;
In the case of the AM Low-Cut function is not needed, set up the value of C3 over 1 F. In the condition
of C3 ≥ 1 F, the frequency characteristic has flat response at the low frequency.
In FM mode, C3 is a capacitor for AFC Low-Pass filter circuit.
2. FM detection circuit
For the FM detection circuit, detection coil is able to use instead of ceramic discriminator. Recommended
circuit and recommended coil are as follows. In this case, please take care that Vin (lim.) falls a little.
