NTE1236
Integrated Circuit
TV Sound IF System
Description:
The NTE1236 monolithic TV/FM sound system consists of a multistage limiting IF amplifier, DC gain
control, FM detector, and an audio driver constructed on a single silicon chip. Excellent sensitivity,
high AM rejection and an internally regulated power supply coupled with low external component re-
quirements makes the NTE1236 suitable for a wide variety of applications including TV sound chan-
nels, FM radios and mobile communications equipment.
Features:
D Electronic Attenuator Replaces Conventional Volume Control
D High Sensitvity
D Low Harmonic Distortion
D Excellent AM Rejection: (5−dB typ. at 4.5MHz)
D Internal Zener Diode Regulated Supply
D Differential Peak Detector Requires Only One Single−Turned Coil
Absolute Maximum Ratings: (T_A = +25°C, unless otherwise specified)
