Overview
The LA3370 is a multiplex IC for FM car stereo, and it has
the following 2 functions through its utilization of the IF
meter output voltage, etc.
1. Stereo noise control (SNC) under which the noise
particular to the FM stereo unit in the weak electric
field is reduced smoothly.
2. High-cut control (HCC) under which the high
frequency is smoothly attenuated. In additioin, the
LA3370 can be, due to its low distortion factor, an IC
for multiplex stereo demodulator which is appropriate
for the car component stereo unit.
Functions
Stereo noise control (SNC terminal)
Through controlling the quality of sound from stereo mode to monaural mode with the voltage applied to the control
pin, the FM stereo noise in the weak electric field is reduced by this function.
High-cut control function (HCC terminal)
The FM noise in the weak electric field is reduced through the attenuation of high frequency thereof.
Such attenuation can be changed smoothly from "Normal" to "High Cut" by controlling the voltage applied to the
control pin. The volume of "High Cut" can be selected by using an external capacitor.
Stereo-monaural automatic select
This selection has priority over the stereo noise control. Pilot input prioritized.
Stoppage of VCO oscillation
When a voltage of 7.5V or higher is applied to the HCC terminal, the oscillation of VCO can be discontinued. In this
case, the stereo lamp does not malfunction.
With separation control terminal.
Features
Low distortion factor. (0.05% typ. 300mV input, mono)
The ripple of power source can effectively be rejected. (35dB typ.)
The range of voltage to be used is wide. (V
CC
=6.5 to 14V)
The space factor is advantageous because of the single-end package.
The printed circuit board can easily be prepared as 3mm pitch is used between the pins.
