Doctors monitor internal patient health with an electrocardiograph machine that uses sensors and electrodes. The detected signals are amplified, filtered, and digitally converted to output waveforms on a display or printer for analyzing abnormalities. Portable electrocardiograph machines allow emergency medical services to perform hospital-quality electrocardiograms in the field and relay that information quickly to doctors in another location. Nationals large power management portfolio of small, low-power chips, combined with its space-saving packaging technology for audio and Bluetooth? wireless technology, allow designers to extend battery life while creating smaller, lighter, and more portable devices.

Component Highlights

* A/D converter - high-speed, 10-bit or greater resolution converters are designed for high-performance medical diagnostic equipment; many include internal sample-and-hold for convenience.

* Operational amplifiers, buffers - Ideal for medical diagnostic and sensing applications, precision operational amplifiers and high-current driver amplifiers have rail-to-rail input and output for best use of the supply voltage range. High-speed buffers are available in several gains and configurations.

* Voltage reference - select from several references with better than 0.2% accuracy to deliver precise voltages of between 1.024V and 10V.
* Voltage supervisor - a broad selection of tiny, flexible voltage supervisors offer manual reset and low-voltage operation.

* Bluetooth technology - space-saving, flexible options from standard products to customizable products to full custom ASICs meet the critical needs of consumer electronics.
