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.

Engineers at Fuel Cell Energy have found a way to take advantage of a side reaction, unique to their carbonate fuel cell that has nothing to do with energy production, as a potential, cost-effective solution to capturing carbon from fossil fuel power plants.
To get to a trillion sensors in the IoT that we all look forward to, there are many challenges to commercialization that still remain, including interoperability, the lack of standards, and the issue of security, to name a few.
This is part one of an article discussing the University of Washington’s nationally ranked FSAE electric car (eCar) and combustible car (cCar). Stay tuned for part two, tomorrow, which will discuss the four unique PCBs used in both the eCar and cCars.
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.
