New current sensors have no magnetic circuits
https://www.electronics-lab.com/new-current-sensors-no-magnetic-circuits/
Clemens Valens @ elektormagazine.com discuss about LEM’s new current sensors which do not use the Hall effect make the measurement. Instead they integrate conductors for gradient measurement and provide immunity against the external fields. He writes: Here are some new integrated circuit transducers for AC and DC isolated current measurement up to 300 KHz that […]

by Graham Prophet @ eedesignnewseurope.com discuss about the MAX17682 buck DC-DC converter. With details recently posted by Maxim integrated, MAX17682 is a high-voltage, high-efficiency, iso-buck DC-DC converter designed to provide isolated power up to 10W. The device operates over a 4.5V to 42V input voltage range and uses primary-side feedback to regulate the output voltage. […]
AS7261 Color sensor from Ams
https://www.electronics-lab.com/as7261-color-sensor-ams/
The AS7261 integrates Gaussian interference filter technology to enable chromatic white color sensor which provides direct XYZ color coordinates consistent with the CIE 1931 2° Standard Observer color coordinates. Additional mapping of XYZ coordinates to the x, y (Y) of the 2-dimensional color gamut and scales of the CIE 1976 u’v’ coordinate system, providing accurate […]
