DESCRIPTION
The LT®6230/LT6231/LT6232 are single/dual/quad low noise, rail-to-rail output unity gain stable op amps that feature 1.1nV/√Hz noise voltage and draw only 3.5mA of supply current per amplifier. These amplifiers combine very low noise and supply current with a 215MHz gain bandwidth product, a 70V/µs slew rate and are optimized for low supply voltage signal conditioning systems. The LT6230-10 is a single amplifier optimized for higher gain applications resulting in higher gain bandwidth and slew rate. The LT6230 and LT6230-10 include an enable pin that can be used to reduce the supply current to less than 10µA.
