Texas Instruments keeps power low, working with voltages as low as 1.8V. The OPA333 uses auto-zeroing techniques to simultaneously provide two microVolt offset and quiescent current of 17 microAmps. High-impedance inputs offer a common-mode range 100mV beyond both rails, with rail-to-rail output that swings within 100mV of the rail.
The CMOS parts also maintain minimal drift over time and temperature. Common-mode rejection ratio doesn't have the crossover errors often associated with many complementary input stages. Auto-zeroing techniques provide very low offset voltage and near-zero drift over time and temperature. SC70, SOT23-5 and SO-8 packages are priced at $0.95 in 1,000 piece orders.

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.
