DESCRIPTIO
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.
The 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 en • √ISUPPLY product of 1.9 per
amplifier is among the most noise efficient of any op amp.
The LT6230/LT6230-10 is available in the 6-lead SOT-23
package and the LT6231 dual is available in the 8-pin SO
package with standard pinouts. For compact layouts, the
dual is also available in a tiny dual fine pitch leadless
package (DFN). The LT6232 is available in the 16-pin
SSOP package.
