NE572
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.
Key Features
- Independent control of attack and recovery
- Improved low frequency gain control ripple
- Complementary gain compression and expansion with external op amp
