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  
Rev. E
