TDA7012 Single-chip FM receiver

The TDA7012T FM radio receiver integrated circuit is very simple, yet this FM receiver offers good sensitivity and selectivity. The single-chip TDA7012T FM receiver can be built with only a few additional components. The features included in the TDA7012T FM receiver integrated circuit are quite attractive for FM receivers. These include a micro-sensitivity arrangement (MTS) for low-voltage applications, a frequency-locked loop (PLL) to 76 kHz range, and FM receiver selectivity using an RC filter.
