Small Signal Response, RF = 0 Ω, 50 Ω 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 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. |
