There are several ways to produce a negative voltage from a positive voltage source, including using a transformer or two inductors and/or multiple switches. However, none are as easy as using the LTC3863, which is elegant in its simplicity, has superior efficiency at light loads and reduces parts count compared to alternative solutions. Advanced Controller […]

This Design Idea is a solid state relay (SSR) which uses a triac to switch AC loads at high current. There are plenty of simple SSR circuits available, but this may be the simplest circuit that achieves turn-on and turn-off only when the AC line voltage is near zero. Figure 1Â AC SSR schematic with

Multifunction data-acquisition systems have been around for a long time as stand-alone instruments, plug-in cards, cabled computer peripherals, and embedded in systems. Such systems are often designed with separate ADCs, DACs, and digital I/O devices. Many microcontrollers include ADCs and DACs, but that locks you into using that device. The AD5592R from Analog Devices combines

We already know, that Switches MEC Unimec switch in up to eight ways and also that they´re available as momentary or alternate (latching). UNIMEC switches feature perhaps only one “disadvantage” – that on the same PCB no other higher components can be used (which would be higher than the switch). If you´re satisfied with the
