Parametric evaluation tool aids op amp
selection
Analog Devices has developed a new parametric evaluation tool for amplifiers that enables system designers to select, evaluate and troubleshoot its range of voltage feedback operational amplifiers.
Analog Devices has developed a new parametric evaluation tool for amplifiers that enables system designers to select, evaluate and troubleshoot its range of voltage feedback operational amplifiers By using parametric data to mathematically model the general behaviour 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

A/D convertor achieves a new level of 16bit data capture performance, with best-in-class 15bit ENOB and 10Msample/s throughput.
The tool, available to users at no charge, is accessible in real-time on the Analog Devices website and requires no software download.
"For years, 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".

Combined two-chip solution can reduce the active component count by 60% within a radio design, providing considerable board area and bill of material savings.
"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".
The 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 redesigns 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.
