Overview
The LT1013DID from Texas Instruments is a dual precision operational amplifier, known for its high performance and versatility. This device is part of the LT1013 series, which features high gain, low supply current, low noise, and a low-offset-voltage temperature coefficient. The LT1013DID can operate from a single 5-V power supply or dual ±15-V supplies, making it suitable for a wide range of applications. The common-mode input voltage range includes ground, and the output can swing to within a few millivolts of ground, eliminating crossover distortion.
