Chip beads and inductors carry robust soft terminations
TDK Corporation presents the world’s first multilayer chip beads and inductors with the innovative soft-termination technology that is already proven in TDK MLCCs. The external electrodes of the new KMZ1608 and KPZ1608 series of chip beads and the KLZ1608 and KLZ2012 series of inductors feature a conductive resin layer that offers effective protection against board […]
How should grounds and commons be connected to each other?
We have already looked briefly at Earth ground (if any), chassis ground, and commons (often misnamed as “grounds”). These do not exist as unrelated connections in a system. The issues related to connecting commons and ground is the subject of countless articles, academic papers, vendor application notes, anecdotes, and even books. There are many rules […]
MLCCs surpass 100uF
Through continued technical innovation and material sciences advancements, Murata Electronics has developed Hi-Cap MLCCs which surpass 100uF. The line is offered in three new capacitance offerings: 150uF, 220uF, and 330uF values which are available in a range of voltages and case sizes, such as: -1206 size / X5R / 150uF & 220uF /2.5V or 4V -1210 size / X5R / 220uF & 330uF / […]
What are the different “grounds” in electronic design?
The term “ground” is one of the most frequently used words in electronics, and it’s also one of its most-often misused and misunderstood terms. Fortunately, in many cases of misuse, the engineers using it know what it actually being referred to, and are able to translate it internally and so avoid negative consequences. However, there […]
Ultra-low power accelerometer for IoT asset-health monitoring
Analog Devices, Inc. announced a next-generation accelerometer designed for long-period monitoring of the physical condition of high-value assets. With its extremely low power capabilities, the ADXL372 micropower high-g MEMS accelerometer targets Internet of Things (IoT) solutions where shock and impact on a unit during storage, transit, or use would adversely affect its function, safety, or […]
What are some specialized op amp variations?
The operation amplifier – commonly called the op amp – is the key building block of analog circuits. In its basic configuration, it is most often used to amplify a signal, of course. It can also be configured to perform mathematical operations such as implementing multiplication or division of two signals, take a square root, […]
STiD135 demodulator chip targets satellite use
STMicroelectronics announced the volume production of the world’s first 500Mbaud High Symbol Rate (HSR) integrated tuner-demodulator chip, selected by its lead customer Newtec, a specialist in designing, developing, and manufacturing equipment and technologies for satellite communications. Designed to increase bandwidth-usage efficiency and throughput in high-end satellite and hybrid broadband-broadcast applications, the STiD135 demodulator supports the […]
High-throw count RF switches span 9 kHz – 8 GHz range
Peregrine Semiconductor Corp., founder of RF SOI (silicon on insulator) and pioneer of advanced RF solutions, introduces the UltraCMOS® PE42562, PE42582 and PE42512 high-throw count RF switches. Optimized for the demands of next-generation test & measurement equipment, these SP6T, SP8T and SP12T absorptive switches support a wide frequency range from 9 kHz to 8 GHz […]
Working with op amps: tying down floating pins
Operational amplifiers are used in many configurations and with many variations on specifications, depending upon the application. However, an IC package of operational amplifiers will often come with several in a package (e.g., a “quad pack” will have four op amps). If you have leftover, unused op amps on the same chip, the unused ones […]
