GENERAL DESCRIPTION (continued)
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 V step and 65 ns to 0.01% on a 10 V step.
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.
