Avoiding op-amp output saturation error by keeping op-amp outputs “live” and below zero volts is a job where a few milliamps and volts (or even fractions of one volt) of regulated negative rail can be key to achieving accurate analog performance...
Zero-voltage switching flyback topology and advanced SR FET control enable 95 percent efficiency, reduce power supply size and component count...
Relays are common electromechanical devices in electrical circuits that come in two types: either latched or non-latched...
Bel Fuse announced the industry’s only surface mount, PPTC resettable fuse, line-volt-rated to 240 VAC...
Single-output switching regulator circuits can often be adapted to multiple output configurations with a minimum of changes, but these transformations usually call for custom wound inductors...
Fig 1’s circuit, which was developed to monitor the traffic of bumblebees into and out of the hive, differentiates “a-to-b” motion from “b-to-a” motion...
This issue had been previously addressed during pre-internet times in EDN of January 18,1990 but a further detailed look at the idea is warranted thirty-four years later...
Here is the circuit from a previous DI. Simple local low-noise voltage converter that can be used when a simple negative supply of low voltage is required. It is simple, and its efficiency can be improved by a very quick change...
Large currents flowing in a length cable can be measured using the voltage drop along the cable. It eliminates the need for a bulky shunt or expensive magnetic measurement method...
