TV Sound Circuit  
Description:  
The NTE748 is an integrated circuit in a 14–Lead DIP type pacjage designed for IF limiting, detection,  
audio preamplifier and driver for the sound portion of a TV receiver.  
Features:  
D Excellent Limiting with 80µV(rms) Input Signal typ  
D Large Output–Voltage Swing–to 3.5V(rms) typ  
D High IF Voltage Gain–65dB typ  
D Zener Power–Supply Regulation Built–in  
D Short–Circuit Protection  
D A Coincidence Discriminator that Requires Only One RLC Phase Shift Network  
D Preamplifier to Drive a Single External–Transistor Class–A Audio Output Stage  
Absolute Maximum Ratings: (TA = +25°C unless otherwise specified)
