LT6236/LT6237/LT6238
Rail-to-Rail Output
215MHz, 1.1nV/√Hz
Op Amp/SAR ADC Driver
DescripTion
The
LT
®
6236/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.
