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.

Festo's BionicKangaroo combines pneumatic and electrical drive technology, plus very precise controls and condition monitoring. Like a real kangaroo, the BionicKangaroo robot harvests the kinetic energy of each takeoff and immediately uses it to power the next jump.
Design News and Digi-Key presents: Creating & Testing Your First RTOS Application Using MQX, a crash course that will look at defining a project, selecting a target processor, blocking code, defining tasks, completing code, and debugging.
