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.
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
REV. C

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

... ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD818 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. – ...

... OFFSET NULLING The input offset voltage of the AD818 is inherently very low. However, if additional nulling is required, the circuit shown in Figure 5 can be used. The null range of the AD818 in this configuration is ± 10 mV. SINGLE SUPPLY OPERATION Another exciting feature of the AD818 is its ability to perform well in a single supply configuration ...

... Measuring the rapid settling time of the AD818 ( 0.1% and 0.01%—10 V step) requires applying an input pulse with a very fast edge and an extremely flat top. With the AD818 configured in a gain of –1, a clamped false summing junction responds when the output error is within the sum of two diode voltages (approximately 1 V) ...
