NTE1842 Datasheet | NTE Electronics

Description : The NTE1842 is a FM/AM IF system IC in a 16- Lead DIP type package designed for portable use. As pared 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: 7m A, FM: 10m A (Typ) D Low Number of External ponents D Excellent Tweet D Low Overvoltage Distortion D Tuning Indicator LED Driving Capability: ILAMP = 10m A (Max) D Built- In FM/AM Mode Switch D mon Output for FM/AM D Operating Supply Voltage Range: VCC9opr) = 3V to 8V Absolute Maximum Ratings: (TA = +25°C unless otherwise specified) Supply Voltage, VCC - - - - - - - - - - - - - 8V Lamp Current, ILAMP - - - - - - - - - - - - . . 10m A Power Dissipation, PD - - - - - - - - - - - . . . 750m W Derate Above 25°C - - - - - - - - - - - 6m W/°C Operating Temperature Range, Topr - - - - - - - . . . . - 25°C to +75°C Storage Temperature Range, Tstg - - - - - - - - . . - 55° to +150°C DC Characteristics: (VCC = 5V, Pin Voltage at No Signal) Typical Parameter Pin1 Voltage (AM Mix Input) Pin2 Voltage (AM Mix Bypass) Pin3 Voltage (AM OSC) Pin4 Voltage (Reg) Symbol V1 V2 V3 V4 AM 1.5 1.5 2.3 2.3 FM 0 0 2.3 2.3 Unit V V V V DC Characteristics (Cont’d): (VCC = 5V, Pin Voltage at No...
