DescripTion

The LT

®

6233/LT6234/LT6235 are single/dual/quad low

noise, rail-to-rail output unity-gain stable op amps that

feature 1.9nV/√Hz noise voltage and draw only 1.2mA of

supply current per amplifier. These amplifiers combine

very low noise and supply current with a 60MHz gain-

bandwidth product, a 17V/µs 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 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 e

n

• √I

SUPPLY

product of 2.1 per amplifier

is among the most noise efficient of any op amp.

The LT6233/LT6233-10 are 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.
