ADI LT6237HMS8#PBF

The LT6236/LT6237/LT6238 are single/dual/quad low noise, rail-to-rail output op amps that feature 1.1nV/√Hz input referred noise voltage density 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 and a 70V/µs slew rate. Low noise, fast settling time and low offset voltage make this amplifier optimal to drive low noise, high speed SAR ADCs. The LT6236 includes a shutdown feature that can be used to reduce the supply current to less than 10µA. This amplifier family has an output that swings within 50mV of either supply rail to maximize the signal dynamic range in low supply applications and is specified on 3.3V, 5V and ±5V supplies. The LT6236/LT6237/LT6238 are upgrades to the LT6230/ LT6231/LT6232, offering similar performance with reduced wideband noise beyond 100kHz.
