Am715/715C High-Speed Operational Amplifier Description: The Am715 and Am715C high-speed op- erational amplifiers are functionally, electrically, and pin-for-pin equivalent to the Fairchild A715 and #A715C. Both are available in the hermetic metal can, dual-in-line, and flat packages. Distinctive Characteristics: 100% reliability assurance testing including high-temperature bake, temperature cycling, centrifuge and fine leak hermeticity testing in compliance with MIL-STD-883. Electrically tested and optically inspected dice for the assemblers of hybrid products. FUNCTIONAL DESCRIPTION FUNCTIONAL DIAGRAM The Am is adifferential input, single-ended output operational Vey CASCODE amplifier having wide bandwidth and high slew rate. It has internal lead compensation and four points for external lag compensation networks, providing many possible combina- tions of frequency compensation. In addition, a point is INVERTING INPUT Q=-- brought out for use with an external diode to prevent latch-up ae ran Amit5 ouTPUT in voltage follower applications.

Ska LIC-735 = Figure 1 The high gain and large bandwidth of the Am715 make it mandatory to observe the following precautions in using the device, as is the case with any high frequency amplifier. Circuit layout should be arranged to keep all lead lengths as short as possible and the output separated from the inputs and frequency compensation pins. The values of the feedback and source impedances should be kept small to reduce the effect of stray capacitance of the inputs. The power supplies must be bypassed to ground at the supply leads of the amplifier with low inductance capacitors. Capacitive loading must be kept to an absolute minimum, since the amplifier cannot tolerate more than 30 pF directly at its output with full feedback.
