The AD8009 is an ultrahigh speed current feedback amplifier
SFDR
with a phenomenal 5,500 V/µs slew rate that results in a rise
–66 dBc @ 20 MHz, Second Harmonic
time of 545 ps, making it ideal as a pulse amplifier.
–75 dBc @ 20 MHz, Third Harmonic
The high slew rate reduces the effect of slew rate limiting and
Third Order Intercept (3IP)
results in the large signal bandwidth of 440 MHz required for

Supply Operation
The AD8009 is capable of delivering over 175 mA of load current
