AM Radio Receiver Circuit Employs FM IC Chip

This AM receiver consists of a TDA7000 single-chip FM receiver (U1) as the main radio component,  and an LM386  chip for low-voltage audio-power amplifier (U2) circuit. The receiving coils are  hand-wound coils (L1 and L2), and a few additional components.  This coils, together with the variable capacitor, is chosen to match the AM frequency. To …

AM Radio Receiver Circuit Using TDA 1072AT IC

TDA 1072AT is a special purpose integrated circuit for AM radio receiver from Philips Semiconductors. The integrated circuit is designed for mains-fed home receivers and car radios. 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. RF radiation and …
