GENERAL DESCRIPTION

The AD8368 is a variable gain amplifier (VGA) with analog linear-in-dB gain control that can be used from low frequencies to 800 MHz. Its excellent gain range, conformance, and flatness are attributed to the Analog Devices, Inc., X-AMP? architecture, an innovative technique for implementing high performance variable gain control.
