PRODUCT DESCRIPTIONThe AD818 is a low cost, video op amp optimized for use in
video applications which require gains equal to or greater than
+2 or –1. The AD818 low differential gain and phase errors,
single supply functionality, low power and high output drive
make it ideal for cable driving applications such as video cam-
eras and professional video equipment.
With video specs like 0.1 dB flatness to 55 MHz and low differ-
ential gain and phase errors of 0.01% and 0.05°, along with
50 mA of output current, the AD818 is an excellent choice for
any video application. The 130 MHz 3 dB bandwidth (G = +2)
AD818 Video Line Driver
and 500 V/µs slew rate make the AD818 useful in many high
speed applications including: video monitors, CATV, color
copiers, image scanners and fax machines.
The AD818 is fully specified for operation with a single +5 V
power supply and with dual supplies from ±5 V to ±15 V. This
power supply flexibility, coupled with a very low supply current
of 7.5 mA and excellent ac characteristics under all power
supply conditions, make the AD818 the ideal choice for many
demanding yet power sensitive applications.
The AD818 is a voltage feedback op amp and excels as a gain
stage in high speed and video systems (gain = >2 or –1). It
achieves a settling time of 45 ns to 0.1%, with a low input offset
voltage of 2 mV max.
The AD818 is available in low cost, small 8-lead plastic mini-
DIP and SOIC packages.

ESD SUSCEPTIBILITYESD (electrostatic discharge) sensitive device. Electrostatic
charges as high as 4000 volts, which readily accumulate on the
human body and on test equipment, can discharge without de-

tion circuitry, permanent damage may still occur on these
devices if they are subjected to high energy electrostatic dis-
