Overview
The LT1013DIP, produced by Texas Instruments, is a dual precision operational amplifier. 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 LT1013DIP can operate from a single 5-V power supply or dual ±15-V supplies, making it versatile for various applications. It features an input voltage range that extends to ground and an output that can swing to within a few millivolts of ground, eliminating crossover distortion.
