Current-sense amplifier integrates shunt resistor

Current-sense amplifier integrates shunt resistor
Claimed to be the industry’s first current-sense amplifier to integrate a high-precision, low-drift shunt resistor, which can deliver highly accurate measurements over a wide temperature range, the INA250 has been unveiled by Texas Instruments. This integration also enables lower system cost and a smaller board footprint compared to competitive solutions.

Hermetic hybrid DC/DC converters are rated at 185ºC

Hermetic hybrid DC/DC converters are rated at 185ºC
The industry’s first hermetic hybrid DC/DC converters rated at 185ºC in a 1” wide package has been introduced by IR HiRel, an Infineon Technologies company. The devices are designed specifically for oil and gas exploration downhole tools and can withstand the high temperature as well as the high shock environment typically found in these applications. As oil and gas are more and more difficult to find, exploration takes place in environments which are challenging and where temperatures are higher.
