The AD8009 is an ultrahigh speed current feedback amplifierwith a phenomenal 5,500 V/μs slew rate that results in a risetime of 545 ps, making it ideal as a pulse amplifier.The high slew rate reduces the effect of slew rate limiting andresults in the large signal bandwidth of 440 MHz required forhigh resolution video graphic systems. Signal quality is maintainedover a wide bandwidth with worst-case distortion of–40 dBc @ 250 MHz (G = +10, 1 V p-p). For applications withmultitone signals, such as IF signal chains, the third orderintercept (3IP) of 12 dBm is achieved at the same frequency. Thisdistortion performance coupled with the current feedbackarchitecture make the AD8009 a flexible component for a gainstage amplifier in IF/RF signal chains.The AD8009 is capable of delivering over 175 mA of load currentand will drive four back terminated video loads while maintaininglow differential gain and phase error of 0.02% and 0.04°,respectively. The high drive capability is also reflected in theability to deliver 10 dBm of output power @ 70 MHz with–38 dBc SFDR.The AD8009 is available in a small SOIC package and willoperate over the industrial temperature range –40°C to +85°C.The AD8009 is also available in an SOT-23-5 and will operateover the commercial temperature range of 0°C to 70°C.
