Simultaneous sampling ΣΔ ADCs improve signal quality monitoring
Analog Devices has introduced a series of 24-bit simultaneous sampling ΣΔ ADCs for wide-bandwidth, high-density instrumentation, energy and healthcare equipment. The AD7768 series includes a power scalable modulator and digital filter on each channel to enable the synchronised, precise measurement of both AC and DC signals in instrumentation applications, including modular data acquisition, audio test, and asset condition mo...
24-60W AC/DC power supplies suit medical applications
The TMM series of fully encapsulated 24 to 60W AC/DC power supply modules, available from Powersolve, have been designed specifically for medical applications although their EMI/EMC characteristics and safety approval package combine to make the modules suitable for demanding applications in industrial and transportation systems.
PCB relays need only half the space of previous-generations
Schukat aims to be your partner of choice when it comes to relays. With Zettler, the company now has another well-known manufacturer among its relay suppliers. Zettler's AZ956 series PCB relays stand out with their super-small dimensions. At just 13x7.62x6.9mm, they require only half the space of previous-generation standard relays.
Power doubler MCMs provide easy upgrade to DOCSIS 3.1
Qorvo has unveiled three DOCSIS 3.1-ready power doubler multi-chip modules (MCMs). Qorvo’s latest power doubler MCM amplifiers provide cable broadband service providers an easy upgrade path to DOCSIS 3.1 with maximum design flexibility and functionality while conserving power and reducing board space.

GaN-on-Si power transistors suit use in macro wireless basestations
MACOM has announced the latest entries in its MAGb series of GaN on Silicon power transistors for use in macro wireless basestations. Based on MACOM’s Gen4 GaN technology, the MAGb-101822-240B0P and MAGb-101822-120B0P power transistors harness the clear performance benefits of GaN in rugged, low-cost plastic packaging, enabling improved cost efficiencies that further distinguish MACOM’s GaN power transistors as the natural s...
Origami ninja star inspires super efficient battery
A disposable battery that folds like an origami ninja star could power biosensors and other small devices for use in challenging field conditions, says an engineer at Binghamton University, State University of New York. Seokheun "Sean" Choi, assistant professor of computer and electrical engineering at Binghamton University, along with two of his students, developed the device, a microbial fuel cell that runs on the bacteria available in a few dr...
Fuel gauges monitor battery life in mobile devices
The MAX1720x and MAX1721x ModelGauge m5 battery fuel gauges from Maxim Integrated are now in stock at Mouser Electronics. These ultra-low power, stand-alone fuel gauge ICs feature low quiescent currents and programmable alert functions for voltage, temperature, current, and state of charge (SOC).
Next-gen batteries use a pigment electrode
Calcium ion batteries (CIBs) have attracted much attention as next-generation batteries to replace lithium ion batteries (LIBs) because the theoretical capacity of CIBs is twice that of LIBs. This doubled capacity can be explained by the difference between monovalent and divalent ions. In addition, CIBs possess advantages such as a lower cost and higher safety because calcium is more abundant than lithium and because CIBs have a higher melting po...
