Linear Technology LT1638/LT1639 Operational Amplifier Datasheet
The document describes the LT1638, a low power dual operational amplifier, and the LT1639, a low power quad operational amplifier. Both devices feature rail-to-rail input and output capabilities, allowing them to operate with inputs above the positive supply voltage (Over-The-Top). They are designed for battery-powered systems, portable instrumentation, and sensor conditioning applications.
