6233/LT6234/LT6235 are single/dual/quad low
noise, rail-to-rail output unity gain stable op amps that
feature 1.9nV/鈭欻z 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/碌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
10碌A(chǔ).
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
鹵5V
supplies. The e

product of 2.1 per
amplifier is among the most noise efficient of any op amp.
The LT6233/LT6233-10 is available in the 6-lead SOT-23
package and the LT6234 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 LT6235 is available in the 16-pin
SSOP package.
