Analogue and Discretes

The latest figures from European Components Distribution (DMASS) show a decline in Q1 of 23.3% with semiconductor revenue dropping by 26.5%. DMASS Europe’s chairman, Hermann Reiter, was keen to stress there is no cause for alarm, saying that this market consolidation was long overdue. “Everyone should have prepared to weather a few quarters of weak bookings and billings,” he said, ...

Although engineers design predominantly digital systems, they will always need some analogue knowledge, say Scott Carson and Jed Boyer. The drive to minimise power consumption in everyday devices via digitisation means much of the infrastructure needed to power these devices is largely analogue at its core. With analogue design being such a critical skill for systems engineers, it is quite ...

The diverse challenges facing 5 distinct product segments. When it comes to electronics, most designs will involve multiple semiconductor devices. With this point in mind, Rochester Electronics’ goal is not to offer a single solution for an obsolete device, but instead provide a range of solutions covering the many mature devices likely found in designs. For example, finding a solution ...

Vishay has introduced a photovoltaic mosfet gate driver qualified to AEC-Q102 for automotive use. Called VOMDA1271, “the component is available in a SOP-4 housing. The driver is the only one of its kind in this package size with an isolation voltage of 3.750 V [sic] and a typical open-circuit output voltage of 8.5V”, according to component distributor Rutronik, which is ...

Winner Analog Devices – AD4130-8 The AD4130-8 adds digital features to a low power sigma delta ADC, which is in a smaller size package while keeping precision. The power consumption is improved by an order of magnitude compared to competitive devices, while adding functionality and features helps system designers to make designs recyclable and accelerates time to market. The AD4130-8 ...

The latest ECSN UK/Ireland electronic components market forecast for 2023 indicates the market is ‘back to normal’ but still subject to geo-political issues as well as relying on management of the grey market and readjusted inventory. Beginning the briefing with a reference to the Hitchhiker’s Guide to the Galaxy, Aubrey Dunford, market analyst at ECSN (pictured), declared that for the ...

Ash Madni, WIMMIC’s Technical Director, tells how his lifelong adventure in electronics began with the discovery of the world of Bipolar transistors, namely the BC108… It all started when I was 13 years old at school. A class mate was an Electronics hobbyist and during break, he talked animatedly about what he was going to build over the weekend. My ...

Orolia has introduced a ruggedised version of its mRO-50 miniature (51 x 51 x 20mm) rubidium atomic clock. Called ‘mRO-50 Ruggedized’, its vibration rating has been raised from 4Grms to 7.7Grms (lock retained, MIL-STD-810H method 514.8 annex E – was annex C), and shock raised from 30G to 50G (MIL-STD-202G 11ms half sine) – qualification to the shock rating is ...

STMicroelectronics has released a silicon carbide T-switch module for three-level dc-dc converter topologies (right), and also a single-phase full-bridge. Both are rated at 1.2kV, 75A and contain four of the company’s second-generation 13mΩ SiC mosfets, in its 48 x 57mm Acepack power package which can be press-fitted or soldered. The package (left) has Cu-Al2O3-Cu substrates for good thermal conductivity. Junction ...

LSI Computer Systems (LSI/CSI) has created a family of 63 tap (6bit) digital potentiometers for direct connection to quadrature decoders, push buttons, GPIOs or SPI serial controls. Debounce circuits are included where electromechanical switches are expected, although external pull-up resistors must be added. “The LSI/CSI digital potentiometers are used as replacements for mechanical potentiometers and for potentiometer adjustments,” according to distributor Omni ...
