Overview
The LT1013DMD is a variant of the LT1013x series of dual precision operational amplifiers produced by Texas Instruments. These amplifiers are known for their high precision, low noise, and robust performance characteristics. The LT1013DMD can operate from a single 5-V power supply or dual ±15-V supplies, making it versatile for various applications. The device 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. It is characterized for operation over a wide temperature range, making it suitable for both commercial and military-grade applications.
