LT6221 - Dual 60MHz, 20V/µs Low Power, Rail-to-Rail Input and Output Precision Op Amp

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.
