GENERAL DESCRIPTION
The AD8061/AD8062/AD8063 are rail-to-rail output voltage
feedback amplifiers offering ease of use and low cost. They have
a bandwidth and slew rate typically found in current feedback
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/AD8063 provide
excellent overall performance. For video applications, their
differential gain and phase errors are 0.01% and 0.04° into a
responsibility is assumed by Analog Devices for its use, nor for any infringements of patents or other
rights of third parties that may result from its use. Specifications subject to change with out notice. No
license is granted by implication or otherwise under any patent or patent rights of Analog Devices.

150 Ω load, along with 0.1 dB flatness out to 30 MHz. Additionally, they offer wide bandwidth to 300 MHz along with
650 V/µs slew rate.
The AD8061/AD8062/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 µA. These features
make the AD8063 ideal for portable and battery-powered
applications where size and power are critical.

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
MAXIMUM POWER DISSIPATION
The maximum power that can be safely dissipated by the
AD8061/AD8062/AD8063 is limited by the associated rise in
junction temperature. The maximum safe junction temperature
for plastic encapsulated devices is determined by the glass
transition temperature of the plastic, approximately 150°C.
Temporarily exceeding this limit may cause a shift in parametric
performance due to a change in the stresses exerted on the die
by the package. Exceeding a junction temperature of 175°C for
an extended period can result in device failure. While the
AD8061/AD8062/AD8063 is internally short-circuit protected,
this may not be sufficient to guarantee that the maximum
junction temperature (150°C) is not exceeded under all
conditions.
To ensure proper operation, it is necessary to observe the
maximum power derating curves.
