00 — Overview

What the LT6230 does

The LT6230/LT6230-10/LT6231/LT6232 family comprises single, dual, and quad low noise, rail-to-rail output unity-gain stable operational amplifiers. These devices feature 1.1nV/√Hz noise voltage, 3.5mA maximum supply current per amplifier, 215MHz to 1450MHz gain bandwidth product, and 115dB typical common mode rejection ratio. The parts operate across a 3V to 12.6V supply range and support output swings within 50mV of either rail. Engineers typically use them for ultrasound amplifiers, low noise signal processing, active filters, driving A/D converters, and as rail-to-rail buffer amplifiers in commercial and industrial temperature grades.
