This is information on a product in full production.March 2013DocID2155 Rev 31/13LM119, LM219, LM319High-speed dual comparatorsDatasheet - production dataFeatures•Two independent comparators •Supply voltage: +5 V to ±15 V •Typically 80 ns response time at ±15 V •Minimum fan-out of two each side•Maximum input current of 1 µA over the operating temperature range •Inputs and outputs can be isolated from system ground •High common-mode slew rateDescriptionThese products are precision high-speed dual comparators designed to operate over a wide range of supply voltages down to a single 5 V logic supply and ground. They feature low input currents and high gains.The open collector of the output stage makes them compatible with transistor-transistor logic (TTL) as well as capable of driving lamps and relays at currents up to 25 mA.Although designed primarily for applications requiring operation from digital logic supplies, these comparators are fully specified for power supplies up to ±15 V.They feature faster response times than the LM111 at the expense of higher currentconsumption. However, the high speed, wide operating voltage range and low package count make the LM119, LM219, and LM319 much more versatile.Contents LM119, LM219, LM319Contents1Schematic diagram . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 2Absolute maximum ratings and operating conditions . . . . . . . . . . . . . 4 3Electrical characteristics . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5 4Typical application diagrams . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 95Package information . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 105.1DIP14 package information . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 105.2SO-14 package information . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .11 6Ordering information . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 12 7Revision history . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 122/13DocID2155 Rev 3LM119, LM219, LM319Schematic diagramdiagram1 SchematicFigure 1.

Laryngograph Ltd’s LxStrobe3 vs KayPentax’s Digital Strobe History To compare the LxStrobe3 and the Kay Digital Strobe (KDS) properly it is important to understand the history both of the products and of the companies that provide them.
The KDS was developed in the early 1990s, and improved upon existing stroboscopy equipment by computerising the acquisition of images. Subsequently Kay have added an image processing component and an option for videokymography. The Kay Computerised Speech Laboratory (CSL), comprising tools originally developed for speech analysis by phoneticians, engineers and speech pathologists, is available as a separate component.
Laryngograph stroboscopy has been developed in three stages. Version 1 gave the highest quality uncompressed digital images then available, with automatic acquisition and animation of vocal fold image sequences within a single glottal period. Version 2 (LxStrobe2) emulated the KDS approach in fully computerising the acquisition of continuous stroboscopic images with sophisticated playback and editing facilities. The final stage, LxStrobe3, is an enhanced version of LxStrobe2, which offers uncompressed quality video capture and full HD 1920x1080 support.
Speech Studio, Laryngograph’s voice analysis software, encapsulates 25 years of research into voice by Laryngograph Ltd and its academic and clinical collaborators. It is the only system in the world which is specifically designed for the analysis of voice in connected, real-life, pathological speech. (i.e. analysis of samples of continuous speech, typically of two minutes, either taken from conversation or reading aloud.)
Product comparison 1. LxStrobe3 and Kay 9295B take a different approach in capturing and compressing video streams. LxStrobe3 uses an extremely high quality RGB frame grabber from world famous industrial/scientific/medical imaging supplier Matrox to stream uncompressed RGB video to computer, then uses a software video codec to compress the video in real time. The combined hardware/software approach offers great flexibility and best performance. LxStrobe3 also allows uncompressed still image capturing and video streaming in uncompressed format to hard drive. This choice It is the currently preferred method in high quality industrial/scientific/medical imaging systems.
KDS uses a video capture/ hardware compressing card from an unnamed company. The card takes only S-Video input and therefore has lower quality in digitized video. Due to the hardware compressing of the card, it is not possible to have uncompressed still images or video sequences.
LxStrobe3 uses either the Toshiba IK-TU62 3CCD camera or the Sony DXC-C33P which many clinicians are familiar with from the imaging stacks used in theatre. Instead of using S-Video like Kay, LxStrobe3 uses the RGB video output from the camera for best quality. The resolution of the image is the same on both systems, 768 x 576, and both capture 50 fields per second. The LxStrobe3 image gives bright, unblinking and sharp images throughout a normal pitch range from 55Hz to 1450Hz. 2. There is only one type of Laryngograph system. The video is digitised as described in 1) and stored as an avi file on the storage drive. The archiving system is a DVD+RW drive using disks with a 4.7GB capacity. LxStrobe3 stores recorded video files under patient session folders. Users can simply use Windows Explorer to archive video files to DVD+RW media by drag-and-drop. Files are written to DVD+R media using Nero software. In the next software release it will be possible to write a file to a DVD disk from the strobe program, delete the file from and then defragment the hard drive.
LxStrobe avi files can be used straight away with Windows Media Player in any Windows XP/2000 systems without any conversion. However, users of Kay systems have to do extra work to convert their recordings to industrial standard formats to be used on other computers.
3. LxS streams 50 fields of video data per second to the capture drive. There is no skipping or jumping in the image and no black frames. It provides superb views of the mucosal wave and glottal edge movement. We can provide testaments from LxStrobe users who have diagnosed any number of “leading edge” subtleties of vocal fold pathology.
4. The LxStrobe PC can be networked provided anti-virus software does not interfere with real time video capturing.
