AD8009ARZ (ANALOG DEVICES)

The AD8009ARZ is a 1GHz Low Distortion Current Feedback Amplifier with a phenomenal 5500V/µs slew rate that results in a rise time of 545ps 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 440MHz required for high resolution video graphic systems. For applications with multitone signals, such as IF signal chains, the third order intercept (3IP) of 12dBm is achieved at the same frequency. This distortion performance coupled with the current feedback architecture makes it a flexible component for a gain stage amplifier in IF/RF signal chains. The AD8009 is capable of delivering over 175mA 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 10dBm of output power at 70MHz with -38dBc SFDR.
