NTE1392 & NTE1393
Integrated Circuit
Audio Power Amp, 7W
Description:
The NTE1392 and NTE1393 are class B power amplifiers in a 10–Lead SIP type package designed
especially for home tpe stereo amplifiers. These devices provide an output power of 5W at 19V, and
also 7W at 22V to an 8Ω load with 10% distortion.
Features:
D Available in Two Different Pin Configurations:
Normal – NTE1392
Reverse – NTE1393
D High Output Power: 7W Typ (VCC = 22V, RL = 8Ω, THD = 10%)
D Wide Range of Supply Voltage: 5V to 30V
D Very Low Harmonic and Crossover Distortion
D Thermal Shut–Down Circuit Provided
Absolute Maximum Ratings: (TA = +25°C unless otherwise specified)
