NTE1842 Integrated Circuit FM/AM IF System
Description: The NTE1842 is a FM/AM IF system IC in a 16-Lead DIP type package designed for portable use. As compared with conventional ICs, this device is greatly improved in external parts counts and electrical characteristics, espeically tweet and overload distortions. Features: D Low Supply Current, AM: 7mA, FM: 10mA (Typ) D Low Number of External Components D Excellent Tweet D Low Overvoltage Distortion D Tuning Indicator LED Driving Capability: ILAMP = 10mA (Max) D Built-In FM/AM Mode Switch D Common Output for FM/AM D Operating Supply Voltage Range: VCC9opr) = 3V to 8V Absolute Maximum Ratings: (TA = +25C unless otherwise specified) Supply Voltage, VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8V Lamp Current, ILAMP . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10mA Power Dissipation, PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 750mW Derate Above 25C . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6mW/C Operating Temperature Range, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -25C to +75C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -55 to +150C DC Characteristics: (VCC = 5V, Pin Voltage at No Signal)
