Rail-to-Rail Output Swing
Input offset voltage is trimmed to less than 60µV. The low n 120dB Minimum Voltage Gain, VS = ±15V drift and excellent long-term stability guarantee a high ac- n 0.8µV/°C Maximum VOS Drift curacy over temperature and time. The 300pA maximum n 14nV/√Hz Input Noise Voltage input bias current and 120dB minimum voltage gain further n 2.7V to ±18V Supply Voltage Operation maintain this precision over operating conditions. n Operating Temperature Range: –40°C to 85°C n Space Saving 3mm × 3mm DFN Package The LT6011/LT6012 work on any power supply voltage from 2.7V to 36V and draw only 135µA of supply current on a 5V supply. The output swings to within 40mV of
