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.

Single in the 8-Pin SO and 5-Pin Low Profile
(1mm) ThinSOTTM Packages
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.

Dual in the 8-Pin SO and (3mm x 3mm) DFN
Packages
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
availableinthe16-PinSSOPpackage.TheLT6220/LT6221/
LT6222 can be used as plug-in replacements for many op
amps to improve input/output range and performance.
