LT6220/LT6221/LT6222
Single/Dual/Quad 60MHz,
20V/µs, Low Power, Rail-to-Rail Input
and Output Precision Op Amps
DescripTion
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
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 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
×
3mm low profile dual fine pitch leadless) 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.
