PRODUCT DE SCRIPT ION
T he 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. T he 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. T he 130 MHz 3 dB bandwidth (G = +2)

s slew rate make the AD818 useful in many high
speed applications including: video monitors, CAT V, color
copiers, image scanners and fax machines.
T he AD818 is fully specified for operation with a single +5 V
power supply and with dual supplies from
±
5 V to
±
15 V. T his
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.
T he 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.
T he AD818 is available in low cost, small 8-pin plastic mini-
DIP and SOIC packages.
