AM receiver circuit
TDA1572
GENERAL DESCRIPTION
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 variable capacitance diodes. If required, band switching diodes can easily be applied. Selectivity is
obtained using a block filter before the IF amplifier.
Features
Inputs protected against damage by static discharge
Gain-controlled RF stage
Double balanced mixer
Separately buffered, voltage-controlled and temperature-compensated oscillator, designed for simple coils
Gain-controlled IF stage with wide AGC range
Full-wave, balanced envelope detector
Internal generation of AGC voltage with possibility of second-order filtering
Buffered field strength indicator driver with short-circuit protection
AF preamplifier with possibilities for simple AF filtering
Electronic standby switch
IF output for stereo demodulator and search tuning.
