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 Ω） 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 Ω 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.
