Is it Possible to operate with single supply +5v ?
AD8188, with Standartd PAL CVBS inputs is it possible to connect only the positve rail of power supply VS+ - 5v
and the -VS to connect to GND.
Hi Moshe,Unfortunately no, the minimum operating range of the device is +/-4V.Regards.
Hi Moshe,AD8188 can be operated at single supply, your PAL input has has horizontal sync which is 0.7V below the GND level. You need to clamp it to the proper DC level in order for the device to accept the whole composite signal without losing its integrity.Regards,
