Ordering number: EN3210A
Overview
The LA1806 is a characteristics-improved version of the
LA1811, with the same pin assignment and package as those of
the LA1811. Improvements are made on the following points:
.
Separation (35 dB
48 dB) and its dependence on
free-running frequency (Refer to the separate catalog of the
LA1805.)
.
FM main distortion (0.8%
.
AM detection output (approximately 5 dB increased)
The constants on five external parts are changed as LA1811
Functions
.
FM-IF: IF amplifier quadrature detector, soft muting, tuning
indicator
.
MPX: PLL stereo decoder, stereo indicator, forced
monaural, VCO stop
.
AM:
RF amplifier, MIX, OSC (with ALC), IF amplifier,
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
