LTC6412 Datasheet (Linear Technology Corporation) - 31dB Range Analog-Controlled VGA

LTC6412, 31dB Range Analog-Controlled VGA

The LTC®6412 is a fully differential variable gain ampliﬁer with linear-in-dB analog gain control.

It is designed for AC-coupled operation in IF receiver chains from 1MHz to 500MHz.

The part has a constant OIP3 across a wide output amplitude range and across the 31dB gain control range.
