Overview
The LT1013DD is a dual precision operational amplifier produced by Texas Instruments. This device is part of the LT1013x series, known for its high gain, low supply current, low noise, and low-offset-voltage temperature coefficient. The LT1013DD can operate from a single 5-V power supply or dual supplies ranging from ±3 V to ±18 V. It features a common-mode input voltage range that includes ground, and the output can swing to within a few millivolts of ground, eliminating crossover distortion.
