Differences between LA1805 and LA1806
(1) Same pin assignment
(2) The internal circuit of the MPX OUT (pin 9, pin 10) is different as shown below.
The FM S curve at pin 17 is in the opposite direction and the circuit in which AFC is provided is the same for the
US band and Japanese band.
(Cu-foiled area)
The LA1805 contains the output load resistors
(Output load resistance=6.8k
)
For the LA1806, output load resistors R
L
, R
R
are connected-
xternally. The graph of demodulation output vs. R
L
(R
R
) is
shown below.
