INTEGRATED CIRCUITS DATA SHEET TDA1572T AM receiver Product specification File under Integrated Circuits, IC01 May 1992 Philips Semiconductors Product specification AM receiver GENERAL DESCRIPTION The TDA1572T 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 variable capacitance diodes.
