3 Description
The LT1013x devices are dual precision operational amplifiers, featuring high gain, low supply current, low noise, and low-offset-voltage temperature coefficient.
The LT1013x devices can be operated from a single 5-V power supply; the common-mode input voltage range includes ground, and the output can also swing to within a few millivolts of ground. Crossover distortion is eliminated. The LT1013x can be operated with both dual ± 15-V and single 5-V supplies.
The LT1013C and LT1013D are characterized for operation from 0°C to 70°C. The LT1013DI is characterized for operation from −40°C to 105°C. The LT1013M, LT1013AM, and LT1013DM are characterized for operation over the full military temperature range of −55°C to 125°C.
