Overview
The LT1013DDR 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 LT1013DDR can operate from a single 5-V power supply or dual ±15-V supplies, making it versatile for various applications. The common-mode input voltage range includes ground, and the output can swing to within a few millivolts of ground, eliminating crossover distortion.
