* The FM output level forms an N curve (LA1805) and an S curve (LA1806).
LA1805: N curve (for US band)
LA1806: S curve (for Japanese band). Since an output load resistor is connected to pins 9, 10 externally, your desired output
level can be set by varrying the output resistance.
Operating Characteristics at Ta = 25°C, VCC = 4.5 V, See specified Test Circuit.
