Analog Devices Inc. (ADI, Wilmington, MA) 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. The tool, available to users at no charge, is accessible in real-time on the company's website, and requires no software download. The tool can be accessed at http://www.analog.com/designcenter/ampevaltool.
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.
