LA1805
No.2887-3/13
Test Circuit
Polystyrene film capacitor
Differs from the application circuit
where a front end is used.
(See Sample Application Circuit
on page 10.)
How to use the LA1805
1. Forced monaural mode.
Figures 1 and 2 show how to cause the forced monaural mode to be entered.
(1) Connect pin 14 to V
CC
through a resistor of 100k
. (Turn ON the SW1 in Figure 1.)
(2) Connect pin 15 to GND through a resistor of 47k
. (Turn ON the SW2 in Figure 2.)

Figure 2 Forced Monaural Mode Setting Method
Unit (resistance :
, capacitance : F)
Either above-mentioned (1) or (2) causes the forced
monaural mode to be entered. In this case, the VCO
does not stop operating. If the resistance of R1 and
R2 are decreased, internal bias will vary when the S1
or S2 is turned ON. This data is shown in Figure 3.
