Part Number: TDA7421N
Function: HIGH PERFORMANCE FRONT-END IC FOR AM/FM RECEIVER
The TDA7421N is a high-performance tuner circuit which integrates AM and FM sections, PLL frequency sinthesizer and IF counter on a single chip.
Use of BICMOS technology allows the implementation of tuning functions with a minimum of external components.Value spread of external components can be fully compensated by means of on-chip electrical adjustment controlled by external µP.
