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 wind your won coil, L1 […]

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 sensitivity to interference are minimized […]
