Overview
The LT1013CP is a dual precision operational amplifier produced by Texas Instruments. It is characterized by its high gain, low supply current, low noise, and low-offset-voltage temperature coefficient. This device can operate from a single 5-V power supply or dual supplies ranging from ±3 V to ±18 V. The common-mode input voltage range includes ground, and the output can swing to within a few millivolts of ground, eliminating crossover distortion.
