With increasing demand for accessible medical care, the need for portable diagnostic imaging equipment is growing. Much of the existing equipment is bulky, extremely expensive, and consumes excessive power. Ultrasound is the least invasive, most mobile imaging technology and with a much lower per scan cost than other options, it is positioned for the fastest growth.  MORE

A portable pulse oximeter is an instrument that measures blood oxygen saturation. What differentiates this from traditional blood oxygen monitors is that it is done noninvasively. Typically such an instrument has a pair of small LEDs at 660 nm and Infrared (IR) wavelengths facing photodiodes through a translucent part of the patient's body, usually a fingertip. Learn More.

National’s SIMPLE SWITCHER power modules save time and make it easier to design for applications with demanding power supply requirements.

Easy-to-use SIMPLE SWITCHER® power modules feature a new innovative package and deliver best-in-class EMI and thermal performance. The power modules provide high efficiency over a wide input voltage and load current range and are pin-to-pin compatible for different load currents.

The LMV7231 is a 1.5% accurate Hex Window Comparator which can be used to monitor power supply voltages. The device uses an internal 400mV reference for the comparator trip value. The comparator set points can be set via external resistor dividers. The LMV7231 has 6 outputs (CO1-CO6) that signal an under-voltage or over-voltage event for each power supply input. An output (AO) is also provided to signal when any of the power supply inputs have an over-voltage or under-voltage event. This ability to signal an under-voltage or over-voltage event for the individual power supply inputs, in addition to an output to signal such an event on any of the power supply inputs adds unparalleled system protection capability.

The LMH1983 is a highly-integrated programmable audio/video (A/V) clock generator intended for broadcast and professional applications. It can replace multiple PLLs and VCXOs used in applications supporting SMPTE serial digital video (SDI) and digital audio AES3/EBU standards. It offers low-jitter reference clocks for any SDI transmitter to meet stringent output jitter specifications without additional clock cleaning circuits.
