LA1805
No.2887-1/14
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 freerunning frequency (Sep - fF Characteristic on page 5).
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 11.
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.
Specifications
Maximum Ratings at Ta=25°C, See specified Test Circuit.
