AD8009

1千兆赫， 5500 V / Я低失真放大器 1 GHz, 5,500 V/Я Low Distortion Amplifier

Product Details

The 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.

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% & 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. The AD8009 is also available in an SOT-23-5 and will operate over the commercial temperature range of 0°C to 70°C.

An evaluation board is available for this product and may be ordered using the following product number: AD8009-EB.
