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 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-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) pack­ages with the standard op amp pinout. The LT6222 fea­tures 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.
