- A Numerical Protection Relay SolutionPDF, 187 Kb, Archivo publicado: sept 2, 2010
Numerical Protection Relays (NPRs) are critical elements in any power distribution network. Generally, there are several different types of NPRs. Each type, however, shares a similar architecture, thus enabling designers to build an entire system solution that is based on a relatively small number of flexible components. This application note demonstrates how an NPR can be implemented using TI's e - Determining Minimum Acquisition Times for SAR ADCs, part 2PDF, 215 Kb, Archivo publicado: marzo 17, 2011
The input structure circuit of a successive-approximation register analog-to-digital converter (SAR ADC) incombination with the driving circuit forms a transfer function that can be used to determine minimum acquisition times for different types of applied input signals. This application report, which builds on Determining Minimum Acquisition Times for SAR ADCs When a Step Function is Applied to
