Vreg
A voltage of 1.3 V or higher turns on the post-
amplifier output muting. A voltage of 4.0 V or higher
turns on the IF buffer output.
The recommended control voltage for turning
muting on is 1.9 V.
The AM SD sensitivity can be adjusted with the
resistor inserted between this pin and ground.
Since the FM SD sensitivity is affected by this
resistor, the AM SD sensitivity must be adjusted
first.
Recommended narrow band ceramic filter: BFU450
C4N (Murata Mfg. Co., Ltd.)
The LA1835 switches to AM mode when this pin is
connected to ground.
If a current of 50 A or larger flows from this pin, the
LA1835 switches to mono mode.
The VCO is stopped if this pin is connected to
ground.
Output impedance: ro = 200
Pin 16: left output
Pin 17: right output
Inverting inputs, ri = 3.3 k
Pin 18: left input
Pin 19: right input
