1 / 13 page LA1805 Ordering number : EN2887B AM/FM-IF/MPX Tuner System for Radio-Casette Recorders, Music Centers Monolithic Linear IC SANYO Electric Co.,Ltd. Semiconductor Bussiness Headquarters TOKYO OFFICE Tokyo Bldg., 1-10, 1 Chome, Ueno, Taito-ku, TOKYO, 110 JAPAN 12798HA (KT)/D0994JN/4030MO/N148YT, TS No.2887-1/13 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 – fF 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. Specifications Maximum Ratings at Ta=25°C, See specified Test Circuit.
