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.
