|ANALOG DEVICES’ ONLINE DESIGN TOOL SPEEDS AMPLIFIER EVALUATION AND
Norwood - Analog Devices Inc. (NYSE: ADI), the world leader in amplifiers, today
announced the availability of a parametric evaluation tool for amplifiers that enables system designers to select,
evaluate and troubleshoot voltage feedback operational amplifiers (op amps) from Analog Devices. By using parametric
data to mathematically model the general behavior of a selected amplifier, designers are able to select a component,
quickly configure a circuit, apply a signal and evaluate the amplifier’s general performance.
designers have been forced to rely on tedious hand calculations and guesswork in the selection and evaluation of op
amps,” said Dave Kress, director of applications engineering at Analog Devices. “As such, designers did not always
have the liberty to thoroughly consider all the factors in their selection process. As the world’s leading supplier
of op amps, with a portfolio of thousands of products, we wanted to provide a tool that could simplify the process.
With ADI’s online parametric evaluation tool, our customers can now quickly and efficiently conduct real-time
simulations and troubleshoot potential problems across various parameters and architectures.”
parametric evaluation 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.
The new evaluation tool also offers several key 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. This feature greatly diminishes the
possibility of costly re-designs to a circuit, provides reassurance that the circuit can meet performance objectives
and supports troubleshooting efforts. In addition, a selection Wizard is offered for less experienced designers who
may require additional help choosing an amplifier. 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, which provides a familiar graphical user interface (GUI) and processes
related computational tasks.
