Integrated Circuit
FM Sound System
Description:
The NTE723 is a monolithic integrated circuit FM detector/limiter and audio preamplifier that requires
a minimum of external components for operation. It includes three stages of IF limiting and a differen-
tial–peak–detection circuit.
Features:
D Simple detector alignment: one coil
D Sensitivity: 3dB limiting voltage 250µV typical at 10.7MHz
D Low harmonic distortion
D Excellent AM rejection 55dB typ. at 10.7MHz
D Internal audio preamplifier
