When Second Sources aren't
James Bryant

We have been manufacturing a system using an Analog Devices' component for many years. Recently our purchasing department bought a consignment of cheaper replacement devices from another company and the whole batch of systems using them failed to work. Every specification on their data sheet is the same as ADI's, and when we test them they are well within those specifications. What is happening?

Components and Methods for Current Measurement
Bryan Yarborough  
2/1/2016   3 comments
Current sensing is used to perform two essential circuit functions. First, it measures “how much” current is flowing in a circuit; information that may be used for power management in a DC/DC power supply to determine essential peripheral loads to conserve power. The second function is to determine when there is “too much” current, or a fault condition.

The Drone Dilemma, Part 2: Legal
Scott Deuty  
1/26/2016   2 comments
There is no doubt that legal subjects intermix with privacy and air space. So the legal subject matter that is referred to herein will focus on drone registration and the development of laws and regulation. Other legal matters such as privacy and air space will be covered separately.

Build a high-voltage linear regulator
Steve Taranovich  
1/12/2016   12 comments
Generating a regulated voltage from input rails exceeding 100 V is challenging. A limited selection of integrated solutions complicates the problem. Creating a discrete voltage regulator enables a low-cost solution, but the design process is involved and requires a deeper understanding of key engineering tradeoffs, with an emphasis on device thermal properties.

Low Power Switched Cap Bandgap
Scott McLeod  
12/13/2015   1 comment
Whether designing a bandgap reference for medical implants, monolithic battery charging or just trying to minimize operating power, a switched capacitor bandgap implementation fits the bill nicely. With a switched cap circuit, the creation of a bandgap voltage is based upon charge transfer as opposed to constantly biased circuitry and thus lends itself well to low power operation.
