Application Notes
- AN-1240 Video Transmission Over Twisted Pair Wire (Rev. C)PDF, 102 Kb, Revision: C, File published: May 1, 2013
The circuits in Figure 1 and Figure 2 transmit NTSC video signals over twisted pair wire. They weredesigned and tested for transmitting video on inexpensive CAT-3 twisted pair wire. Even when transmittingon 1000 feet of wire, good quality color video was displayed on a monitor with an NTSC input. Both thetransmit and receive circuits use the LMH6643 dual op-amp that has the proper bandwidth - AN-1244 Photo-Diode Current-to-Voltage Converters (Rev. B)PDF, 132 Kb, Revision: B, File published: May 1, 2013
Converting the small output current of a photo-diode transducer to a fast responding voltage is oftenchallenging. This application report provides some ways to use high-speed current feedback and voltagefeedback op amps to do the job.
