Product Summary

The TDA7021T integrated radio receiver circuit is for portable radios, stereo as well as mono, where a minimum of periphery is important in terms of small dimensions and low cost. The TDA7021T is fully compatible for applications using the low-voltage micro tuning system (MTS) . The TDA7021T has a frequency locked loop (FLL) system with an intermediate frequency of 76 kHz.
