Exxelia introduced Miniature Micro-Layer (MML) capacitors, a breakthrough technology that allows tremendous size and weight reduction thanks to an unrivaled energy density. MML is a revolutionary new technology that provides the highest capacitance per volume in film capacitors available on the market. Why is it a game-changer? Because an unparalleled energy density of 400 J/dm3 […]
Analog IC Tips
Chip resistors are AEC qualified
Electronics that require high reliability are no longer confined to military, aerospace, medical, or automotive market sectors. Many types of electronic end products now demand the higher reliability provided by automotive-grade resistors. Automotive-grade resistors offer increased reliability without the high cost of established reliability Mil-Standard products which allows engineers to increase the reliability of their […]
Evaluation board helps check out SMD oscillators, VCXOs, TCXO/VCTCXOs
The desire to be able to test oscillators quickly and easily is more than achievable using the IOSC EVBoard. The evaluation board is suitable for measuring most surface mount standard oscillators, VCXOs, or TCXO/VCTCXOs. It is available from IQD, part of the Würth Elektronik eiSos Group, and a selection of distributors. The IOSC EVBoard comes […]
Tolerance analysis distinguishes prototypes from production units
It’s not enough to model and simulate circuit behavior – you also have to investigate the effects of component variations from their nominal values due to unavoidable tolerances. There’s a semi-serious quip that scientists can build one of anything – but just one; it takes engineers and production experts to build it again and again […]
Compact micro buzzer features 2-mm profile, SPL of 65 dBA at 10 cm
CUI Devices’ Audio Group announced the introduction of a 3.2 mm x 3.2 mm magnetic transducer buzzer, making it among the smallest micro buzzers in the industry. As the latest addition to CUI Devices’ micro buzzers line, the CMT-322-65-SMT-TR features a low profile of 2 mm, surface mount packaging, and a sound pressure level (SPL) of 65 dBA at 10 […]
Optical links for spacecraft, Part 2: Projects and progress
Using laser-sourced light beams rather than wireless RF to link spacecraft with Earth offers the possibility of a significant increase in data rates. Still, there are significant technical challenges to the concept. The previous part of the article established the need for higher-speed data links to spacecraft and their missions and looked at some of […]
Optical links for spacecraft, Part 1: The throughput limitation
Using laser-sourced light beams rather than wireless RF to link spacecraft with Earth offers the possibility of a significant increase in data rates. Still, there are significant technical challenges to the concept. Scientists, engineers, and researchers communicating with spacecraft have a problem: there’s so much data coming from these spacecraft – and to send to […]
Clamshell 94-GHz sockets handle BGA484 packages
A new BGA socket design uses high-performance elastomer capable of 94 GHz, low inductance and wide temperature applications. The GT-BGA-2159 socket is designed for a 19×19-mm package size and operates at bandwidths up to 94 GHz with less than 1 dB of insertion loss. The socket is designed with a clamshell lid with an adjustable […]
Class-D stereo amplifier drives 12 W and 4Ω speakers
Diodes Incorporated introduces the PAM8965 Class-D stereo audio power amplifier with an integrated synchronous boost converter. This high-efficiency device is targeted for use in AI-enabled speaker systems and portable musical instruments – where elevated output power, extended battery life, and compact construction are all key requirements. Running off a 2.8V to 8.5V supply, the PAM8965 has […]
Transimpedance amplifier signal-to-noise
The use of opamps as a transimpedance amplifier is well known and a good analysis of the noise behavior of them is in the old Burr Brown Application Bulletin AB-076 from 1994. This is still available from Texas Instruments’ website as sboa060 – simply search for that on their website. Improving the signal to noise […]
