AD811SE/883B GENERAL DESCRIPTION

A wideband current feedback operational amplifier, the AD811is optimized for broadcast-quality video systems. The −3 dBbandwidth of 120 MHz at a gain of +2 and the differential gainand phase of 0.01% and 0.01° (RL = 150 Ω) make the AD811 anexcellent choice for all video systems. The AD811 is designed tomeet a stringent 0.1 dB gain flatness specification to a bandwidth of35 MHz (G = +2) in addition to low differential gain and phaseerrors. This performance is achieved whether driving one or twoback-terminated 75 Ω cables, with a low power supply currentof 16.5 mA. Furthermore, the AD811 is specified over a powersupply range of ±4.5 V to ±18 V.The AD811 is also excellent for pulsed applications wheretransient response is critical. It can achieve a maximum slewrate of greater than 2500 V/µs with a settling time of less than25 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 acquisitionsystems due to its low distortion up to 10 MHz and its wide unitygain bandwidth. Because the AD811 is a current feedback ampli-fier, this bandwidth can be maintained over a wide range ofgains. The AD811 also offers low voltage and current noise of1.9 nV/√Hz and 20 pA/√Hz, respectively, and excellent dcaccuracy for wide dynamic range applications.12348765AD811NC–IN+IN–VS+VSNCOUTPUTNCNC = NO CONNECT00866-E-001NC1NC2–IN3NC4NC16NC15+VS14NC13+IN5OUTPUT12NC6NC11–VS7NC10NC8NC9NOTES1.
