Noise-sensitive circuits, such as analog- to-digital converters (ADCs), digital-to-analog converters (DACs), amplifiers, and phase lock loops (PLLs) demand low noise power supplies that require specialized design techniques. And some engineers spend hours trying to figure out how to power these circuits without adding noise.  On Wednesday, September 19, 2012, Jeff Weaver, senior applications engineer from ADI will present “Powering Noise Sensitive Circuits” at the Avnet Power Forum – helping engineers find new ways to dramatically reduce noise.

Jeff’s webinar will address the concerns that designers have about powering noise-sensitive circuits by using switching regulators, such as the ADP2441 or ADP2119. During Jeff’s presentation, engineers will get a better understanding of the various methods for not only approaching, but meeting system requirements. He’ll also introduce tested solutions and layout considerations that must be taken into account when designing for low drop out (LDO) applications.

Special Offer for Power Forum participants: ADP7104 Low Noise 20V Linear Regulator Evaluation board

The ADP7102/ADP7104 evaluation board is used to demonstrate the functionality of the ADP7102/ADP7104 series of low noise linear regulators.

Simple device measurements such as line and load regulation, dropout, and ground current can be demonstrated with just a single voltage source, a voltmeter, an ammeter, and load resistors.
