When what's old is new again, with a twist
20.06.2017 · Articles
The other day, while juggling a pile of recorded and blank videotapes for my VCR (please, no snickering that I still use a VCR!) I realized that what I would really like is a video recorder that combines the virtues of removable storage modules with modern digital technology...
Analog Devices' Small Isolated Gate Drivers Deliver Solutions for Next Generation Power Switch Technology
20.06.2017 · News
Analog Devices announced small form factor isolated gate drivers designed for the higher switching speeds and system size constraints required by power switch technologies such as SiC and GaN, while still providing reliable control over switching characteristics for IGBT and MOSFET configurations...
Build an adjustable high-frequency notch filter
19.06.2017 · Circuits
Although you can obtain universal, resistor-programmable switched-capacitor filters that are configurable as notch filters, most cannot operate at bandwidths higher than 100 kHz. Further, the typically 16- to 20-pin packages do not include a continuous-time, antialiasing filter to prevent spurious signals from appearing at the output...
60V Low IQ Synchronous Step-Down Controller Operates at Up to 2.25MHz for High Power Density
19.06.2017 · News
Analog Devices, Inc., which recently acquired Linear Technology Corporation, announces the LTC7800, a synchronous step-down DC/DC controller that operates at up to 2.25 MHz for reduced circuit size and increased power density. Its low 45 ns minimum on-time enables 24 VIN to 3.3 VOUT conversions while switching at a fixed 2 MHz, avoiding critical noise-sensitive frequency bands including AM radio...
