Ordering number: EN3210A
Monolithic Linear IC
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
