The AD811 is also excellent for pulsed applications where transient response is critical. It can achieve a maximum slew rate of

　　greater than 2500 V/μs with a settling time of less than 25 ns to

　　0.1% on a 2 volt step and 65 ns to 0.01% on a 10 volt step.

　　The AD811 is ideal as an ADC or DAC buffer in data acquisition systems due to its low distortion up to 10 MHz and its

　　wide unity gain bandwidth. Because the AD811 is a current

　　feedback amplifier， this bandwidth can be maintained over a

　　wide range of gains. The AD811 also offers low voltage and

　　current noise of 1.9 nV/√Hz and 20 pA/√Hz， respectively， and

　　excellent dc accuracy for wide dynamic range applications

　　The AD811 is a wideband current-feedback operational amplifier， optimized for broadcast quality video systems. The –3 dB

　　bandwidth of 120 MHz at a gain of +2 and differential gain and

　　phase of 0.01% and 0.01° （RL = 150 ?） make the AD811 an

　　excellent choice for all video systems. The AD811 is designed to

　　meet a stringent 0.1 dB gain flatness specification to a bandwidth of 35 MHz （G = +2） in addition to the low differential

　　gain and phase errors. This performance is achieved whether

　　driving one or two back terminated 75 ? cables， with a low

　　power supply current of 16.5 mA. Furthermore， the AD811 is

　　specified over a power supply range of ±4.5 V to ±18 V.
