INTEGRATED CIRCUITS SA5219 Wideband variable gain amplifier Product specification Replaces data of 1993 Dec 10 IC17 Data Handbook 1997 Nov 07 Philips Semiconductors Philips Semiconductors Product specification Wideband variable gain amplifier SA5219 DESCRIPTION The SA5219 represents a breakthrough in monolithic amplifier design featuring several innovations. This unique design has combined the advantages of a high speed bipolar process with the proven Gilbert architecture. The SA5219 is a linear broadband RF amplifier whose gain is controlled by a single DC voltage. The amplifier runs off a single 5 volt supply and consumes only 40mA. The amplifier has high impedance (1kΩ) differential inputs. The output is 50Ω differential.
