March 18, 2024 — TDK Corporation recently announced the expansion of its Micronas 3D HAL® position sensor family with the launch of the HAR 3920-2100, a new dual-chip sensor for automotive and industrial applications. It was designed to meet the demand for highly accurate both linear and angular position measurements in the presence of disturbing […]
March 12, 2024 — Nexperia has recently launched a new range of 4- and 8-channel analog switches designed to monitor and protect 1.8 V electronic systems. This series of multiplexers includes AEC-Q100 qualified variants intended for use in automotive applications as well as standard versions suitable for a broader range of consumer and industrial applications […]
The single-stage, independently regulated multi-output offline power-supply ICs consolidate AC-DC and downstream DC-DC conversion stages into a single chip, to eliminate post regulators. Many systems today, for example, white goods, industrial systems, displays, emergency lighting, networking, home and building automation, require multiple voltage rails, usually achieved by cascading power devices. Losses in each conversion stage […]
March 7, 2024 — Diodes Incorporated recently released a new automotive-qualified linear LED driver that enables users to independently control the brightness and color of its three channels. Human-centric automotive design is driving the demand for multi-channel LED drivers, which allow vehicle occupants to easily change interior lighting colors to match their mood. By simultaneously […]
Called LT8418, this IC looks very much like the output stage used within the recently announced GaN driving dc-dc controller ICs LTC7890 and LTC7891. Both high-side and low-side outputs have separate pull-up and pull-down connections on the IC package channels so that additional resistors can be used to tune GaN transistor turn-on and turn-off times […]
International Solid-State Circuits Conference in San Francisco always seems to make space for audio amplifier developments, and this year is no exception, with some extraordinary distortion and noise figures from Class-D amplifiers, plus a sophisticated Class-H scheme to improve headphone amplifier efficiency. Starting with that headphone amplifier: Class-H is a way to decrease the dissipation […]
In the modern world, basic electronic components, such as resistors, capacitors, and inductors are often overshadowed by the universally applied microprocessors. However, it is these seemingly insignificant components that form the foundation without which no advanced electronic system could exist. Thanks to them, the basic tasks and functions of electronic circuits can be carried out. […]
Called EPC9195, it is a synchronous buck converter built around a pair of 2.5 x 1.5mm EPC2619 GaN hemts, and an LTC7891 controller IC from Analogue Devices. “48V input is getting popular due to USB PD 3.1 efforts to increase power and to reduce cabling for up to 240W,” according to EPC. The board is […]
Superconducting microstrip photon-number-resolving detector. Credit: Kong (SIMIT). Using single photons as qubits has become a prominent strategy in quantum information technology. Accurately determining the number of photons is crucial in various quantum systems, including quantum computation, quantum communication, and quantum metrology. Photon-number-resolving detectors (PNRDs) play a vital role in achieving this accuracy and have two […]
