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 maintained 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.
