NTE NTE1616 Datasheet
NTE1616
Integrated Circuit
TV Sound IF Amp/Detector, Driver
Description:
The NTE1616 is a TV sound integrated circuit in a 14–Lead DIP type package that can be operated
with no adjustment, using ceramic filters externally . This device contains a DC controlled attenuator,
which has wide effective area and gentle characteristic in the changing, so it is convenient especially
for a remote controlled set.
Features:
D Gentle Changing DC Controlled Attenuator is Convenient for Remote Controlled Sets.
D Operation with Ceramic Filters makes TV Sound Circuit No Adjustment Completely
D SRPP Output Circuit can be Driven Directly
D Muting Works Quickly
D Low Distortion Demodulation
Absolute Maximum Ratings: (TA = +25°C unless otherwise specified)
