NTE1482 Datasheet, PDF (1/2 Pages) NTE Electronics – Integrated Circuit PLL FM Stereo Demodulator w/ Pilot Cancel

NTE1482
Integrated Circuit
PLL FM Stereo Demodulator w/
Pilot Cancel
Features:
D External parts are small. Coil is not used.
D Pilot cancel function built−in.
D Other functions: stereo demodulation, stereo/monaural automatic changeover and stereo indi-
cator lamp driving circuit.
D Stereo indicator lamp lighting and stereo/Monaural changeover operations are synchronous.
D Low distortion by the adoption of 100% local feedback circuit. (0.01% typ., 300mV Monoaural
input.)
D High input impedance (75kΩ typ.)
D High S/N. (86dB typ. 300mV input)
D Distortion factor improved by PLL circuit (0.06% typ. 10kHz, Main−ch input)
