ENIAC (Electronic Numerical Integrator And Computer), the first electronic general-purpose computer, was formally announced on February 15, 1946. ENIAC had been heavily veiled before its first announcement, although its construction contract had been signed by the United States Army on June 5, 1943...
EasyEDA provides new PCB order system and DXF import
09.22.2016 · News
EasyEDA is a free, cloud-based EDA application for drawing circuits, running SPICE simulations, designing PCBs, and even placing orders for fabricating PCBs. Earlier we have released an online Gerber viewing tool to visualize the Gerber files generated by a PCB CAD tool. The tool supports the Gerber RS-274X format, which is an industry-standard image description format for PCBs...
D/A Converter Offers More Accuracy in a Smaller Footprint for Diverse Applications Ranging from Radar to Smartphone Testing
09.21.2016 · News
Analog Devices introduced the AD9164 D/A converter that brings high resolution radar images for designers of military and commercial radar while reducing solution component count. Additionally, for designers of precision instrumentation equipment, such as smartphone testers, the new device ensures improved accuracy as well as speed of test, contributing to faster market-ready time while significantly decreasing tester complexity and size. Thanks to its audio to 6 GHz frequency coverage, the AD9164 D/A converter moves the tester market one step closer to a universal wireless test platform...
Keyboard and display multiplexing - the traditional approach
09.20.2016 · Circuits
Webster’s Dictionary defines “multiplex” as “many” or “multiple”. Coincidentally, in an electronics context the word can have several meanings. Whilst they all share the intention to economize on the number of connections used, there are subtle differences. It can mean combining messages on to a single communications channel for transmission and reception. In a similar vein, it can also mean configuring several continuous inputs (either digital or analog) so that only one is accessed at a time...

Bye-bye ATmega328P, Hello 328PB!
We never have enough peripherals on a microcontroller. Whether it’s hardware-driven PWM channels, ADCs, or serial communication peripherals, we always end up wanting just one more of these but don’t really need so many of those. Atmel’s new version of the popular ATmega328 series, the ATmega328PB, seems to have heard our pleas...
New Cypress Automotive LED Driver Delivers Robust Performance and Minimizes the Bill-of-Material for Headlight Systems

Cypress Semiconductor introduced an automotive LED driver that enables smaller and more cost-effective headlight systems. The new S6BL112A automotive-grade LED driver is the industry’s first to feature synchronous control, which helps it provide industry-leading conversion efficiency, enabling stable performance in a lighting system...
Battery Simulators Check Out Chargers, Over-Discharged Batteries
09.15.2016 · Circuits
The two battery-simulator circuits described here can help you quickly test a battery charger under a normal battery condition and an over-discharged battery condition. The circuits let you set any voltage to see how the device under test works. As shunt regulators, the circuits provide what is referred to, in expensive active power-supply loads, as constant voltage mode...
Solar Panels Gain 30% Additional Power with Maxim's Cell-String Optimizer
09.15.2016 · News
New cell-string optimizer technology from Maxim Integrated Products, Inc. allows photovoltaic (PV) panels to harvest significantly more energy and simplifies design complexity for solar installation projects. Our solar cell optimizers embed the maximum power point tracker (MPPT) function deeper in the photovoltaic system than ever before. You’re no longer constrained by the limits of conventional design or panel-level optimization. No more costly boxes hanging off the back of your panel, no more network cabling or communications gateways, and no more hotspot module stress...
