Tel: 781/329-4700 World Wide Web Site: http://www.analog.com Fax: 781/326-8703 © Analog Devices, Inc., 1999 CONNECTION DIAGRAMS FEATURES High Speed 140 MHz Bandwidth (3 dB, G = +1) 120 MHz Bandwidth (3 dB, G = +2) 35 MHz Bandwidth (0.1 dB, G = +2) 2500 V/ s Slew Rate 25 ns Settling Time to 0.1% (For a 2 V Step) 65 ns Settling Time to 0.01% (For a 10 V Step) Excellent Video Performance (RL =150 ) 0.01% Differential Gain, 0.01 Differential Phase Voltage Noise of 1.9 nV √Hz Low Distortion: THD = –74 dB @ 10 MHz Excellent DC Precision 3 mV max Input Offset Voltage Flexible Operation Specified for 5 V and 15 V Operation 2.3 V Output Swing into a 75 Load (VS = 5 V) APPLICATIONS Video Crosspoint Switchers, Multimedia Broadcast Systems HDTV Compatible Systems Video Line Drivers, Distribution Amplifiers ADC/DAC Buffers DC Restoration Circuits Medical—Ultrasound, PET, Gamma and Counter Applications 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 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. 12 –6 3 –3 0 1M 9 6 10 M 100 M FREQUENCY – Hz G = +2 RL = 150 RG = RFB VS = 5V VS = 15V PRODUCT DESCRIPTION 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 ° (R L = 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 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 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. 0.10 15 0.03 0.01 6 0.02 5 0.06 0.04 0.05 0.07 0.08 0.09 14 13 12 11 10 9 8 7 0.20 0.18 0.16 0.14 0.12 0.10 0.08 0.06 0.04 0.02 SUPPLY VOLTAGE – Volts RF = 649 FC = 3.58MHz 100 IRE MODULATED RAMP RL = 150 GAIN PHASE 16-Lead SOIC (R-16) Package 20-Lead SOIC (R-20) Package +IN NC +V S 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 AD811 NC –IN NC +IN –VS NC NC NC NC OUTPUT NC NC NC = NO CONNECT 3 4 5 6 7 8 9 10 18 17 16 15 14 13 12 11 AD811 NC –IN NC NC –VS NC NC NC +V S NC OUTPUT NC NC NC = NO CONNECT NC NC 1 2 20 19 NC NC NC NC NC NC 20-Lead LCC (E-20A) Package REV.
