LA1805 Datasheet Am / Fm-if / Mpx Tuner System

Manufacturer: SANYO (now Panasonic)

Overview: Ordering number : EN2887C LA1805 LA1805 Monolithic Linear IC AM / FM-IF / MPX Tuner System for Radio-Casette Recorders, Music Centers 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.

Key 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. Parameter Maximum supply voltage Maximum supply current Flow-in current (Indicator drive current) Flow-out current Allowable power dissipation Operating temperature Storage temperature Symbol VCC max ICC max I.
