Product Overview

The LTC6412IUF#PBF 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 1 to 500MHz. The part has a constant OIP3 across a wide output amplitude range and across the 31dB gain control range. The output noise (NF + Gain) is also flat versus gain to provide uniform spurious-free dynamic range (SFDR) of >120dB over the full gain control range at 240MHz. The LTC6412 recovers quickly from an overdrive condition and the EN pin allows for a fast output signal disable to protect sensitive downstream components. Asserting the SHDN pin reduces the current consumption below 1mA for power-down or sleep modes.
