GENERAL DESCRIPTION
A wideband current feedback operational amplifier, the AD811 The AD811 is also excellent for pulsed applications where is optimized for broadcast-quality video systems. The −3 dB transient response is critical. It can achieve a maximum slew bandwidth of 120 MHz at a gain of +2 and the differential gain rate of greater than 2500 V/µs with a settling time of less than and phase of 0.01% and 0.01° (RL = 150 Ω) make the AD811 an 25 ns to 0.1% on a 2 V step and 65 ns to 0.01% on a 10 V step. excellent choice for al video systems. The AD811 is designed to The AD811 is ideal as an ADC or DAC buffer in data acquisition meet a stringent 0.1 dB gain flatness specification to a bandwidth of systems due to its low distortion up to 10 MHz and its wide unity 35 MHz (G = +2) in addition to low differential gain and phase gain bandwidth. Because the AD811 is a current feedback ampli- errors. This performance is achieved whether driving one or two fier, this bandwidth can be maintained over a wide range of back-terminated 75 Ω cables, with a low power supply current gains. The AD811 also offers low voltage and current noise of of 16.5 mA. Furthermore, the AD811 is specified over a power 1.9 nV/√Hz and 20 pA/√Hz, respectively, and excellent dc supply range of ±4.5 V to ±18 V. accuracy for wide dynamic range applications.
