LT6232

The LT 6230/LT6231/LT6232 are single/dual/quad lownoise, rail-to-rail output unity gain stable op amps thatfeature 1.1nV/Hz noise voltage and draw only 3.5mA ofsupply current per amplifier. These amplifiers combinevery low noise and supply current with a 215MHz gainbandwidth product, a 70V/µs slew rate and are optimizedfor low supply voltage signal conditioning systems. TheLT6230-10 is a single amplifier optimized for higher gainapplications resulting in higher gain bandwidth and slewrate. The LT6230 and LT6230-10 include an enable pinthat can be used to reduce the supply current to less than10µA.

The amplifier family has an output that swings within50mV of either supply rail to maximize the signal dynamicrange in low supply applications and is specified on 3.3V,5V and ±5V supplies. The en • ISUPPLY product of 1.9 peramplifier is among the most noise efficient of any op amp.

The LT6230/LT6230-10 is available in the 6-lead SOT-23package and the LT6231 dual is available in the 8-pin SOpackage with standard pinouts. For compact layouts, thedual is also available in a tiny dual fine pitch leadlesspackage (DFN). The LT6232 is available in the 16-pinSSOP package.
