SA572 Datasheet | Philips Semiconductors

INTEGRATED CIRCUITS SA572 Programmable analog pandor Product specification IC17 Data Handbook 1998 Nov 03 Philips Semiconductors Philips Semiconductors Product specification Programmable analog pandor DESCRIPTION The SA572 is a dual-channel, high-performance gain control circuit in which either channel may be used for dynamic range pression or expansion. Each channel has a full-wave rectifier to detect the average value of input signal, a linearized, temperature-pensated variable gain cell (∆G) and a dynamic time constant buffer. The buffer permits independent control of dynamic attack and recovery time with minimum external ponents and improved low frequency...
