NTE862

NTE862 Integrated Circuit Audio Power Amplifier, 5W Description: The NTE862 is a power audio amplifier in a 14−Lead DIP type package designed for use in consumer applications. In order to hold system cost to a minimum, the gain is internally fixed at 34dB. A unique input stage allows the inputs to be ground referenced. The output is automatically self centering to one half the supply voltage. Uses include simple phonograph amplifiers, intercoms, line drivers, teaching machine outputs, alarms, ultrasonic drivers, TV sound systems, AM−FM radio, sound projector systems, etc. Features: D Wide Supply Voltage Range D Low Quiescent Power Drain D Voltage Gain Fixed at 50 D High Peak Current Capability D Input Referenced to GND D High Input Impedance D Low Distortion D Quiescent Output Voltage is at One Half of the Supply Voltage Absolute Maximum Ratings: Supply Voltage, VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 28V Peak Current, ICpeak . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1.3A Power Dissipation (Note 1), PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1.67W Input Voltage, Vin . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ±0.5V Maximum Junction Temperature, TJ . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . +150°C Operating Temperature Range, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0° to +70°C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −65° to +150°C Lead Temperature (During Soldering, 10 sec.), TL . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . +260°C Electrical Characteristics: (Note 2) Parameter Input Resistance Bias Current Symbol ZIN IBIAS Inputs Floating Test Conditions Min − − Typ 150 100 Max − − Unit kΩ nA Note 1.
