GENERAL DESCRIPTION
The TDA 1072AT integrated AM receiver circuit performs the active and part of the filtering functions 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 voltage-controlled oscillator provides signals with extremely low
distortion and high spectral purity over the whole frequency range even when tuning with variable capacitance diodes.
If required, band switching diodes can easily be applied. Selectivity is obtained using a block filter before the IF amplifier.
