PRODUCT DESCRIPTION  
The AD811 is also excellent for pulsed applications where tran-  
sient 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 a wideband current-feedback operational ampli-  
fier, 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 band-  
width 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.  
The AD811 is ideal as an ADC or DAC buffer in data acquisi-  
tion 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 accu-  
racy for wide dynamic range applications.
