any video application. The 130 MHz 3 dB bandwidth (G = +2)

and 500 V/ms slew rate make the AD818 useful in many high speed

applications including video monitors, CATV, color copiers,

image scanners, and fax machines.

Specified for Single (+5 V) and Dual (؎5 V to ؎15 V)

Power Supplies

Low Power: 7.5 mA Max Supply Current

Available in 8-Lead SOIC and 8-Lead PDIP

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 sup-

ply conditions, make the AD818 the ideal choice for many

demanding yet power sensitive applications.

GENERAL DESCRIPTION

The AD818 is a low cost video op amp optimized for use in

video applications that require gains equal to or greater than +2

or –1. The AD818’s 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

cameras and professional video equipment.

The AD818 is a voltage feedback op amp and excels as a gain

stage in high speed and video systems (gain ≥ 2, or gain £ –1). It

achieves a settling time of 45 ns to 0.1%, with a low input offset

voltage of 2 mV max.

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

The AD818 is available in low cost, small 8-lead PDIP and

SOIC packages.
