NTE7067
Integrated Circuit
Audio IF Detector for High Quality
Multi鈥揅hannel TV & VCR
Description:
The NTE7067 is a 4.5MHz to 6.5MHz intercarrier audio IF detector for high鈥搎uality multi鈥揷hannel TV
and VCR sound systems. It is designed for use is quasi鈥損arallel configurations to eliminate audio
buzz and minimize other side鈥揺ffects present in conventional detection circuits.
This device includes a 3鈥搒tage 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鈥揕ead SIP
type package.
