NTE723

NTE723 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 differential–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 Absolute Maximum Ratings: Power Supply Current (Pin5) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 30mA Supply Voltage (Pin5) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 12.5V Power Dissipation (Note 1), PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 715mW Operating Temperature Range, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –40° to +85°C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –65° to +150°C Lead Temperature (During Soldering , 10sec), TL . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . +300°C Note 1.
