... APPLICATIONS INFORMATION Power Supply Considerations The LT6557 is optimized to provide full video signal swing output when operated from a standard 5V single supply. Due to the supply current involved in ultrahigh slew rate amplifi ers like the LT6557, selection of the lowest workable supply voltage is recommended to minimize heat genera- tion and simplify thermal management ...

... PIN16 SET 200kΩ. Shutdown Control The LT6557 may be placed into a shutdown mode, where 9.1k all three amplifi er sections are deactivated and power sup- ply draw is reduced to approximately 10µA. When the EN pin is left open, an internal 40k pull-up resistor brings the + pin to V the pin more than approximately 1 ...
