Analog Devices announced the availability of a parametric evaluation tool for amplifiers. It enables system designers to select, evaluate and troubleshoot voltage feedback operational amplifiers from Analog Devices. By using parametric data to mathematically model the general behavior of a selected amplifier, designers are able to select a component, configure a circuit, apply a signal and evaluate the amplifier’s general performance. The tool, available to users at no charge, is accessible on the Analog Devices Web site and requires no software download (infobox below).
The tool enables designers to check an amplifier’s parametric performance, such as bandwidth limitations, input/output range, gain errors, and DC errors in a given circuit configuration. By observing the limits specified by these parameters, the designer is ensured that the device is safely and reliably operating well within its optimal performance range. It also offers features that aid in the selection of amplifiers from Analog Devices. For instance, once a circuit has been set, a designer can request a list of the amplifiers that would best fit a given design. An ADI customer can then evaluate each component separately to determine which device best suits their design. Separately, interactive message flags issue a series of warnings if a circuit configuration may lead to damage of an amplifier, if the circuit yields degraded performance or if there is an issue the designer should simply be made aware of. In addition, a selection Wizard is offered. This particular option determines circuit configuration and component values and provides suggested amplifiers for a particular circuit design. The ADI op amp evaluation tool is powered by National Instruments LabVIEW.
