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.

Digital healthcare devices and wearable electronic products need to be thoroughly tested, lest they live short, ignominious lives, an expert will tell attendees at UBM’s upcoming Designers of Things conference in San Jose, Calif.
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.
