THE BEL 700 INTEGRATED CIRCUIT
The monolithic integrated circuit BEL 700, in dual-in-line plastic package is designed for use in a.m. and AM/FM radio receivers. The IC design is aimed at maximum circuit flexibility combined with maximum economic suitablity. This versatile integrated circuit contains all the blocks that are required for an AM receiver except for the mixer/oscillator and the detector stages. Similarly for f.m. receiver, the tuner and the ratio detector are to be provided externally. This IC thus incorporates a two stage i.f. amplifier, an a.g.c. circuit, a preamplifier, a driver and a class B audio output stage with quiescent current stabilisation circuits. Novel internal stabilisation circuits ensure uniform sensitivity and very ...
