DC gain than other devices with comparable bandwidth. n Wide Supply Range: 2.2V to 12.6V Typically, the LT6220/LT6221/LT6222 have an input offset n Large Output Current: 50mA Typ voltage of less than 100µV, an input bias current of less than n Low Voltage Noise: 10nV√Hz Typ 15nA and an open-loop gain of 100V/mV. The parts have n Slew Rate: 20V/µs Typ an input range that includes both supply rails and an output n Common Mode Rejection: 102dB Typ that swings within 10mV of either supply rail to maximize n Power Supply Rejection: 105dB Typ the signal dynamic range in low supply applications. n Open-Loop Gain: 100V/mV Typ n Operating Temperature Range: –40°C to 85°C The LT6220/LT6221/LT6222 maintain performance for n Single in the 8-Lead SO and 5-Lead Low Profile supplies from 2.2V to 12.6V and are specified at 3V, 5V (1mm) ThinSOT™ Packages and ±5V supplies. The inputs can be driven beyond the n Dual in the 8-Lead SO and (3mm × 3mm) DFN supplies without damage or phase reversal of the output. Packages The LT6220 is housed in the 8-lead SO package with the n Quad in the 16-Lead SSOP Package standard op amp pinout as well as the 5-lead SOT-23 package. The LT6221 is available in 8-lead SO and DFN
