ZN414Z

The ZN414Z is a 10 transistor tuned radio frequency (TRE) circuit packaged in a 3-pin TO-92 plastic package for simplicity and space economy. The circuit provides a complete R.F amplifier, detector and AGC circuit which requires only six external components to give a high quality A.M tuner.

There are some features of ZN414Z as follows: (1)single cell operation (1.1 to 1.6 V operating range); (2)low current consumption; (3)150 kHz to 3 MHz frequency range (i.e full coverage of medium and long wavebands); (4)easy to assemble, no alignment necessary; (5)simple and effective AGC action; (6)will drive crystal earphone direct; (7)excellent audio quality; (8)typical power gain of 72 dB; (9)minimum of external components required.
