NTE1794 Integrated Circuit Volatge Controlled Amp (VCA) for dbx Noise Reduction System Description: The NTE1794 is a dbx noise reduction system voltage controlled amp (VCA) in an 8-Lead SIP type package designed for use in tape decks and other audio equipment. This device features excellent linearity VCA for wider input level due to super low noise and a high gain NPN/PNP complementary process. Features: D Wide Operating Supply Voltage D Excellent Linearity Control Constant D Low Total Harmonic Distortion D Low Noise Absolute Maximum Ratings: (TA = +25C unless otherwise specified) Supply Voltage, VCC, VEE . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 15V Supply Current, ICC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 30mA Power Dissipation (TA = +75C), PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 330mW Operating Temperature Range, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -20 to +75C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -40 to 125C Recommended Operating Conditions: Parameter Operating Supply Voltage Bias Current Input Level Range Symbol VCC, VEE Note 1 ISET in Test Conditions Min 4 - -40 Typ 12 2.0 - Max 15 - +10 Unit V mA dBV Note 1.
