Packages

Single/Dual/Quad 60MHz,

20V/µs, Low Power, Rail-to-Rail Input

and Output Precision Op Amps

The LT

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 off-

set voltage of less than 100µV, an input bias current of less

than 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 maxi-

mize 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-pin SO package with the

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

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

(3mm × 3mm low profile dual fine pitch leadless) pack-

ages with the standard op amp pinout. The LT6222 fea-

tures the standard quad op amp configuration and is

available in the 16-Pin SSOP package. The LT6220/ LT6221/

LT6222 can be used as plug-in replacements for many op

amps to improve input/output range and performance.
