DESCRIPTIO
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 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.
