型號： NTE7200

類別： 集成電路

描述： Description: The NTE7200 is a monolithic intergrated circuit in an 18-Lead DIP type package designed for use as a stereo transmitter. This device consists of a stereo modulator that creates stereo composite signals, an FM modulator that creates FM signals, and an RF amplifier. The stereo modulator develops composite signals made up of a MAIN (L+R) signal, a SUB (L-R) signal and a pilot (19kHz) signal using 38kHz crystal oscillators. The FM modulator has carriers on the FM broadcast band (75 to 108MHz). The RF amplifier transmits the stereo encoded FM signals and is also a buffer for the FM modulator. The stereo transmitter is equipped with a constant voltage pin for a variable capacitor that is used to finly adjust the FM frequency. Features: ? Low Operating Voltage Range (1.0V to 2.0V) ? Low Power Consumption (3mA Typ) ? Few External Components Required Applications: ? FM Stereo Transmitters ? Wireless Microphones
