Overview
The LA1805 is a characteristics-improved version of the
LA1810, with the same pin assignment and package as
those of the LA1810. Improvements are made on the
following point :
Separation (35dB
→
48dB) and its dependence on free-
running frequency (Sep – f
F
Characteristic on page 4).
FM main distortion (0.8%
→
0.45%).
AM detection output (approximately 5dB increased).
The constants on five external parts are changed as shown
on page 10.
Functions
FM-IF : IF amp, quadrature detector, soft muting, tuning
indicator.
MPX :PLL stereo decoder, stereo indicator, forced
monaural, VCO stop.
AM :RF amp, MIX, OSC (with ALC), IF amp, detector,
AGC, tuning indicator.
Features
FM/AM/MPX functions contained on a single chip.
Minimum number of external parts required.
On-chip FM muting function.
High sensitivity.
Less carrier leak of MPX.
