The LT6221CDD is dual, low power, high speed rail-to-rail input and output operational amplifiers with excellent DC performance. The LT6221CDD feature reduced supply current, lower input offset voltage, lower input bias current and higher DC gain than other devices with comparable bandwidth.
Typically, the LT6221CDD 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 LT6221CDD 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 LT6221CDD is available in 8-lead SO and DFN (3mm × 3mm low profile dual fine pitch leadless) packages with the standard op amp pinout. The LT6221CDD can be used as plug-in replacements for many op amps to improve input/output range and performance.
