PRODUCT DESCRIPTION
The AD8061, AD8062, and AD8063 are rail-to-rail output volt-
age feedback amplifiers offering ease of use and low cost. They
have bandwidth and slew rate typically found in current feed-
back amplifiers. All have a wide input common-mode voltage
range and output voltage swing, making them easy to use on
single supplies as low as 2.7 V.
Despite being low cost, the AD8061, AD8062, and AD8063
provide excellent overall performance. For video applications
their differential gain and phase errors are 0.01% and 0.04
into a 150
Additionally, they offer wide bandwidth to 300 MHz along
with 800 V/ s slew rate.

The AD8061, AD8062, and AD8063 offer a typical low power
of 6.8 mA/amplifier, while being capable of delivering up to
50 mA of load current. The AD8063 has a power-down disable
feature that reduces the supply current to 400 A. These features
make the AD8063 ideal for portable and battery-powered
applications where size and power is critical.

... Figure 49 shows a basic circuit for creating a sync stripper using the AD8061 powered by a single supply. When the nega- tive supply is at ground potential, the lowest potential to which the output can go is ground. This feature is exploited to create a waveform whose lowest amplitude is the black level of the video and does not include the sync level ...

Page 15

... AD8062 can accept ground level input signals and output ground level signals, and thus be used as RGB signal amplifiers. A combination of the AD8061 (single) and AD8062 (dual) can amplify the three video channels of an RGB system. Figure 51 shows a circuit that performs this function. ...
