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.
150 Ω load, along with 0.1 dB flatness out to 30 MHz. Addi-
tionally, 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.
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
