PODCAST Avi Yaron: an engineering entrepreneurial venture into the potential and joy of emotional wellness
The brain of an engineer with a tumor and no technology in sight to completely remove it. A terrible thing to waste and a completely unacceptable situation for engineer entrepreneur Avi Yaron. Four surgeries and an invention later, this Joy Ventures CEO and founder of more than a couple of companies — and the chairman […]
High-voltage analog switch ICs handle medical ultrasound imaging applications
Monolithic Power Systems, Inc. announced its launch of two new high-voltage analog switch ICs, the MP4816A and MP4816, for medical ultrasound imaging applications. Our 180V, 16-channel, analog switches can pass or block transmit signals of up to ±90V and require no high-voltage supplies. Because other legacy solutions require one positive and one negative high-voltage supply, eliminating these two supplies […]

Teardown: The Garmin Forerunner 220 sport watch and heart monitor
Chest-mounted electronics do a more accurate job of counting heart beats than do optical sensors on the wrist. That’s one of the conclusions to come out of a close look at this sport watch aimed at runners. Leland Teschler Executive Editor A sport watch from Garmin called the Forerunner 220 is basically a runner’s watch […]

100-V no-opto flyback regulator delivers up to 24 W, 1-kV Output
Linear Technology Corporation announces the H-grade versions of the LT8304/-1, monolithic flyback regulators with guaranteed operation for junction temperatures as high as 150°C. By sampling the isolated output voltage directly from the primary-side flyback waveform, the part requires no opto-coupler or third winding for regulation. The LT8304 operates over a 3V to 100V input voltage […]
Thin-film-on-ceramic high-density resistor networks designed for reliability
TT Electronics, a global provider of engineered electronics for performance critical applications, has launched the QSOP-C and SOIC-C high-density resistor networks that combine high precision with stability and reliability. By using a ceramic substrate and a relatively large feature size, they offer better cross-talk performance than types based on silicon substrates. With target markets in […]
