Typical applicaTion

Single/Dual/Quad 60MHz,

20V/µs, Low Power, Rail-to-Rail Input

and Output Precision Op Amps

The LT®6220/LT6221/LT6222 are single/dual/quad, low

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

amplifiers with excellent DC performance. The LT6220/

LT6221/LT6222 feature reduced supply current, lower

input offset voltage, lower input bias current and higher

DC gain than other devices with comparable bandwidth.

Typically, the LT6220/LT6221/LT6222 have an input offset

voltageoflessthan100µV,aninputbiascurrentoflessthan

15nA and an open-loop gain of 100V/mV. The parts have

an input range that includes both supply rails and an output

that swings within 10mV of either supply rail to maximize

the signal dynamic range in low supply applications.

The LT6220/LT6221/LT6222 maintain performance for

supplies from 2.2V to 12.6V and are specified at 3V, 5V

and ±5V supplies. The inputs can be driven beyond the

supplies without damage or phase reversal of the output.

The LT6220 is housed in the 8-lead SO package with the

standard op amp pinout as well as the 5-lead SOT-23

package. The LT6221 is available in 8-lead SO and DFN

(3mm

×3mmlowprofiledualfinepitchleadless)packages

with the standard op amp pinout. The LT6222 features the

standard quad op amp configuration and is available in

the 16-lead SSOP package. The LT6220/LT6221/LT6222

can be used as plug-in replacements for many op amps

to improve input/output range and performance.
