DESCRIPTION

The NE572 is a dual-channel,

high-performance gain control circuit in which

either channel may be used for dynamic

range compression or expansion. Each

channel has a full-wave rectifier to detect the

average value of input signal, a linearized,

temperature-compensated variable gain cell

(

∆G) and a dynamic time constant buffer. The

buffer permits independent control of

dynamic attack and recovery time with

minimum external components and improved

low frequency gain control ripple distortion

over previous compandors.

The NE572 is intended for noise reduction in

high-performance audio systems. It can also

be used in a wide range of communication

systems and video recording applications.

FEATURES

• Independent control of attack and recovery

time

• Improved low frequency gain control ripple

• Complementary gain compression and

expansion with external op amp

• Wide dynamic range—greater than 110dB

• Temperature-compensated gain control

• Low distortion gain cell

• Low noise—6µV typical

• Wide supply voltage range—6V-22V

• System level adjustable with external

components

APPLICATIONS

• Dynamic noise reduction system

• Voltage control amplifier

• Stereo expandor

• Automatic level control

• High-level limiter

• Low-level noise gate

• State variable filter
