LA1806
AM/FM-IF/MPX Tuner System for
Radio-Cassette Recorders, Music Centers
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% → 0.45%)}
. _{AM detection output (approximately 5 dB increased)}
The constants on five external parts are changed as LA1811
