NTE7067
Integrated Circuit
Audio IF Detector for High Quality
Multi–Channel TV & VCR
Description:
The NTE7067 is a 4.5MHz to 6.5MHz intercarrier audio IF detector for high–quality multi–channel TV
and VCR sound systems. It is designed for use is quasi–parallel configurations to eliminate audio
buzz and minimize other side–effects present in conventional detection circuits.
This device includes a 3–stage IF amplifier, IF AGC circuit, and transistor intercarrier audio detection
circuit. The NTE7067 operates from a single 8 to 10V power supply and is available in a 9–Lead SIP
type package.
