The LT

power, high speed rail-to-rail input and output operational

amplifiers with excellent DC performance. The LT1803/

LT1804/LT1805 feature reduced supply current, lower

input offset voltage, lower input bias current and higher

DC gain than other devices with comparable bandwidth

and slew rate.

Typically, the LT1803/LT1804/LT1805 have an input off-

set voltage of 350

µV, an input bias current of 125nA and

an open-loop gain of 60V/mV.

The LT1803/LT1804/LT1805 have an input range that

includes both supply rails and an output that swings within

20mV of either supply rail to maximize the signal dynamic

range in low supply applications.

The LT1803/LT1804/LT1805 are specified at 3V, 5V and

±5V supplies and typically maintain their performance for

supplies from 2.3V to 12.6V. The inputs can be driven

beyond the supplies without damage or phase reversal of

the output.

The LT1803 is available in the 8-pin SO package with the

standard op amp pinout and in the 5-pin SOT-23 package.

The LT1804 is available in 8-pin DFN and SO packages

with the standard op amp pinouts. The LT1805 features

the standard quad op amp configuration and is available in

a 14-pin plastic SO package.
