MCP651/2/5 (MCP65X) are the world's first and only op amps to include mCal, an
on-chip calibration circuit that calibrates offset voltage at power-up using an
internal power on-reset detector, or based upon the state of an external
pin. The result is a low initial voltage
offset and a means to minimize drift over time and temperature, which are
extremely important for applications involving instrumentation and sensor
conditioning, because this enables extremely precise measurements. The on-board
calibration circuitry within the MCP65x eliminates the need for external
calibrating components and minimizes software complexity by offering a simple,
single-pin hardware control of the calibration. Relative to a
chopper-stabilized or auto-zeroed amplifier, mCal Technology can provide a more
cost-effective solution and does not have the switching noise inherent to
chopper-stabilized amplifiers. mCal Technology offers a cost-effective, easy-to-use
alternative by eliminating the need for external calibration and can provide a
more cost-effective solution relative to a self-correcting architecture.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
