NTE1578 Datasheet | NTE Electronics

Description : The NTE1578 is an FM front- end integrated circuit in a 16- Lead DIP type package designed for use in car radio and home stereo applications. This device has a built- in AGC driver circuit which improves interference characteristics. It thereby offers advantages such as improved interference characteristics without sacrificing usable sensitivity and the conventional DX- LOCAL change- over switch.
