Powerful and speedy op-amps for video

26 July 2006 Analogue, Mixed Signal, LSI

ON Semiconductor has expanded its high-speed op-amplifier portfolio with 500 MHz to 1,4 GHz devices for high end video applications. The seven new devices of the NCS25xx family use new technologies to achieve the ultra low distortion performance levels required for video applications. The NCS2510 and NCS2511 are current feedback devices of 1,4 GHz and 1,0 GHz respectively. The NCS2511 only consumes 7,5 mA of power versus the 12 mA of the NCS2510. The NCS2535 and NCS2540 are triple op-amps, ideal for driving component video. The NCS2535 is a 1,4 GHz current feedback device with disable; the NCS2540 is a 750 MHz voltage feedback device with disable. The NCS2550 and NCS2552 are voltage feedback devices of 750 MHz. The latter comes with an ultra fast enable feature allowing enable times in the range of 5 ns. The NCS2551 is a voltage feedback device of 500 MHz with a slew rate of 1400 V/μs. It only draws 5,5 mA. These devices will allow video designers to achieve 0,02% differential gain and 0,02 degree differential phase performance, while only consuming up to 12 mA, according to the manufacturer.
