How to implement wire‐break detection and diagnostics in isolated digital inputs

This article presents a simple scheme to implement wire-break detection and diagnostics in isolated digital input modules.

How to use power scaling to maximize power savings in a SAR ADC system

This article describes different elements in an ADC system that consume power, provides methods for calculating total power consumption, and discusses the design of a front-end driving circuit to maximize overall power savings.

It’s about time: How TDR enables predictive maintenance for industrial Ethernet

This article covers the basics of TDR, including how to implement a relatively simple TDR-measurement setup without relying on a high-speed ADC or DAC.

Using a high-freq. switching regulator w/o a linear reg. to power a data-converter system

This article shows how a high-frequency DC/DC converter offers low ripple noise and good power-supply ripple rejection compared to a 400-kHz DC/DC converter followed by an LDO.

Stretching a single‐phase design with a buck controller to support high currents

This article is about pushing the design boundaries of a single-phase buck controller to allow higher current levels than what the parametric tables in the product folders suggest.

Does adaptive pre‐boost control in automotive‐lighting apps boost efficiency?

This article explores whether it’s possible to improve overall efficiency by using adaptive pre-boost control in dual-stage LED driver circuits.

Op amps with complementary‐pair input stages: What are the design trade‐offs?

This article is to clarify the term “rail-to-rail input” with regard to op amps.Similar to how the definitions of “wide bandwidth” and “low offset voltage” have changed over the years, rail-to-rail input can have various meanings.
