Ferrite Beads Demystified
A ferrite bead is a passive device that filters high frequency noise energy over a broad frequency range. It is frequently
connected in series with the power supply rail and often combined with capacitors to ground on either side of the bead to form a low-pass
filter to reduce supply noise. Sounds simple, but in this article the author details several critical design techniques involved with
implementing ferrite beads that must be considered to avoid resonance that can induce noise and ripple in the supply.
Powering GSPS or RF Sampling ADCs: Switcher vs. LDO
The new breed of high-performance GSPS data converters provides systems designers with the ability to sample wider and wider
bandwidths at high levels of dynamic range. The traditional thinking was that in order to achieve its rated dynamic range, high-speed
converters must be powered by linear supplies. However the constant market pressure to reduce overall system power, size, and costs has
brought into question utilizing a more efficient, switching power supply solution. But will switchers work for GSPS ADC applications?
In this article the author compares the two supply approaches in terms of system performance, power efficiency, operational costs,
and BOM savings.
When Second Sources Aren't
Every specification on a second source componentís data sheet is the same as ADI's, but when installed in the end-system, it fails. What is happening?
An Engineering Walk through
Virtual Eval, ADIís Online Data Converter Product Evaluation Tool

evaluation tool called Virtual Eval that employs detailed software models to simulate crucial part performance characteristics without
the purchase of hardware. With this tool you can easily configure a variety of operating conditions and device features to establish
your customized use case and get simulation results within minutes. This article explains it all.
Input ADC Solution Alleviates Power Dissipation and Increased Channel Density Challenges
Space- and power-constrained applications are driving the demand for integrated data acquisition solutions with high channel counts, low power and a compact form factors. This article highlights the design considerations involved with multiplexed data acquisition systems and focuses on an integrated multiplexed input ADC solution that enables those critical applications such as can be found in optical transceivers, wearable medical devices, the Internet of Things (IoT), and other portable instruments.
