GENERAL DESCRIPTION

The AD8061, AD8062, and AD8063 are rail-to-rail output

voltage feedback amplifiers offering ease of use and low cost.

They have 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, and AD8063

provide excellent overall performance. For video applications

their differential gain and phase errors are 0.01% and 0.04° into

a 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, 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 μA. These features

make the AD8063 ideal for portable and battery-powered

applications where size and power are critical.
