| 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.
