Technical Information (continued)
0 V
Standby function can be implemented in the AN5274 by external solution. It is realised by pulling the RF voltage
to low and output voltage would follow RF as shown in the diagram.
The ripple rejection of the AN5274 can be improved by another 15 dB by connecting a capacitor to Pin4.
