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:
DWide Operating Supply Voltage
DExcellent Linearity Control Constant
DLow Total Harmonic Distortion
DLow Noise
Absolute Maximum Ratings: (TA = +25°C unless otherwise specified)
