The LT6233/LT6234/LT6235 are single/dual/quad low noise, rail-to-rail output unity gain stable op amps that feature 1.9nV/Hz noise voltage and draw only 1.15mA of supply current per amplifier. These amplifiers combine very low noise and supply current with a 60MHz gain bandwidth product, a 17V/s slew rate and are optimized for low supply voltage signal conditioning systems. The LT6233-10 is a single amplifier optimized for higher gain applications resulting in higher gain bandwidth and slew rate. The LT6233 and LT6233-10 include an enable pin that can be used to reduce the supply current to less than 10A.
