This is information on a product in full production. September 2013 DocID5304 Rev 3 1/11 UA741 General-purpose single operational amplifier Datasheet - production data Features • Large input voltage range • No latch-up • High gain • Short-circuit protection • No frequency compensation required • Same pin configuration as the UA709 Applications • Summing amplifiers • Voltage followers • Integrators • Active filters • Function generators Description The UA741 is a high performance monolithic operational amplifier constructed on a single silicon chip. It is intended for a wide range of analog applications. The high gain and wide range of operating voltages provide superior performances in integrators, summing amplifiers and general feedback applications. The internal compensation network (6 dB/octave) ensures stability in closed- loop circuits.

Very good contact, well packed, hope to buy from you again.

Does what it says. As with this this type of device it is important to have it mounted so that heat can dissipate. The higher the amperage the hotter the device.

I am always amazed at the cost of automotive or marine costs when a rectifier is needed while these will do the exact same thing if you are a bit technically minded to wire them up.
