This Design Idea mates a precision current source IC with precision difference amp chips to create a programmable current source or sink. The resistor-programmable current source/sink in Figure 1 illustrates the basic topology, taking advantage of tightly matched on-chip resistor ratios instead of relying on absolute tolerances. The IIN current source gives rise to a […]

UT203 provides a lot of user comfort and a very pleasant feature – measuring of a DC current without interrupting a measured circuit. However UT204 is different from its “weaker” brother in one essential thing – it enable measuring of a true RMS value of alternating signals (TRMS). As we know, usual multimeters usually deploy
UT204 is able to measure DC current and also True RMS Read More »
For many applications that require power-supply currents of a few amperes or less, three-terminal adjustable-output linear voltage regulators, such as National Semiconductor’s LM317, offer ease of use, low cost, and full on-chip overload protection. The addition of a few components can provide a three-terminal regulator with high-speed short-circuit current limiting for improved reliability. The
Circuit adds foldback-current protection Read More »
Series 1930 may be probably familiar to you, for example from our article Series 1930 – Double Pole Rocker Switches with IP65. Till now, we had in stock types 1935.x with green and red backlight. We react to your requests for switch with the same excellent properties but without a backlight and for as good

Linear Technology Corporation announced the LT8705, a very high efficiency (up to 98%) synchronous buck-boost DC/DC controller that operates from input voltages above, below or equal to the regulated output voltage. This device has four feedback loops to regulate the input current/voltage, along with the output current/voltage. The input current and voltage feedback loops can
Convert any input voltage from 2.8V to 80V into a fixed output voltage or output current Read More »

The Carrier IP Telephony module will offer intelligence and analysis into the companies, products, and strategies impacting the
Rock Island, IL (PRWEB) July 27, 2005 Inpro/Seal has announced their Motor Grounding Seal (MGS), an innovative bearing isolator/grounding seal that stops the damaging effects from destructive residual shaft currents on AC motors. Specifically developed for VFD controlled AC motor applications, it prevents pitting, fluting, fusion craters and eliminates catastrophic motor failure while permanently protecting
MALVERN, Pa. (PRWEB) August 5, 2005 Vishay Intertechnology, Inc. (NYSE: VSH) today announced two new 150-mA low-noise low-dropout (LDO) regulators with the highest available current density in the small five-pin SC-70 package. Their extremely small 2 mm by 2 mm footprint makes them well-suited for use in battery-powered equipment such as cell phones, PDAs, pagers,
NORWOOD, Mass. (PRWEB) September 25, 2008 “Low-power and low-noise operation are key design challenges for mobile device designers being tasked with adding new features and functions into power-sensitive consumer, industrial and medical devices,” said Arcadio Leon, marketing director for portable power products, Analog Devices. “Part of ADI’s growing portfolio of power management solutions, the ADP120,
Melbourne, Florida (PRWEB) January 10, 2012 In response to the devastating impact of the flooding in Thailand on the hard drive market, DTx Inc. partnered with industry experts from Avnet and Intel Corporation to educate electronics designers and manufacturers about the current and future state of the market as well as risk mitigation strategies.
