Overview
The LT1013DIPG4, produced by Texas Instruments, is a dual precision operational amplifier part of the LT1013x series. These devices are characterized by their high gain, low supply current, low noise, and low-offset-voltage temperature coefficient. The LT1013D can operate from a single 5-V power supply, and its common-mode input voltage range includes ground. The output can swing to within a few millivolts of ground, eliminating crossover distortion. This amplifier is suitable for various applications requiring precision and reliability.
