INTEGRATED CIRCUITS DATA SHEET TDA1572 AM receiver circuit Product specification File under Integrated Circuits, IC01 December 1987 Philips Semiconductors Product specification AM receiver circuit GENERAL DESCRIPTION TDA1572 The TDA1572 integrated AM receiver circuit performs all the active functions and part of the filtering required of an AM radio receiver. It is intended for use in mains-fed home receivers and car radios. The circuit can be used for oscillator frequencies up to 50 MHz and can handle RF signals up to 500 mV. RF radiation and sensitivity to interference are minimized by an almost symmetrical design. The controlled-voltage oscillator provides signals with extremely low distortion and high spectral purity over the whole frequency range, even when tuning with variab [ ... ]
