Tel: 781/329-4700 World Wide Web Site: http://www.analog.com Fax: 781/326-8703 © Analog Devices, Inc., 2000 1 GHz, 5,500 V/ s Low Distortion Amplifier FUNCTIONAL BLOCK DIAGRAM 8-Lead Plastic SOIC (SO-8) 5-Lead SOT-23 (RT-5) PRODUCT DESCRIPTION The AD8009 is an ultrahigh speed current feedback amplifier with a phenomenal 5,500 V/ µs slew rate that results in a rise time of 545 ps, making it ideal as a pulse amplifier. The high slew rate reduces the effect of slew rate limiting and results in the large signal bandwidth of 440 MHz required for high resolution video graphic systems. Signal quality is main- tained over a wide bandwidth with worst case distortion of –40 dBc @ 250 MHz (G = +10, 1 V p-p). For applications with multitone signals such as IF signal chains, the third order Intercept (3IP) of 12 dBm is achieved at the same frequency. This distortion performance coupled with the current feedback architecture make the AD8009 a flexible component for a gain stage amplifier in IF/RF signal chains. The AD8009 is capable of delivering over 175 mA of load current and will drive four back terminated video loads while maintaining low differential gain and phase error of 0.02% and 0.04 ° respectively. The high drive capability is also reflected in the ability to deliver 10 dBm of output power @ 70 MHz with –38 dBc SFDR. The AD8009 is available in a small SOIC package and will operate over the industrial temperature range –40 °C to +85°C. –30 –80 –40 –50 –60 –70 –100 –90 2ND, 150 LOAD 2ND, 100 LOAD 3RD, 150 LOAD 3RD, 100 LOAD G = 2 RF = 301 VO = 2V p-p FREQUENCY RESPONSE – MHz 1 200 10 100 Figure 2.
