Differential Phase Error PRODUCT DESCRIPTION Low Distortion
The AD8011 is a very low power, high speed amplifier designed
–70 dBc Worst Harmonic @ 5 MHz
to operate on +5 V or ± 5 V supplies. With wide bandwidth,
–62 dBc Worst Harmonic @ 20 MHz
low distortion, and low power, this device is ideal as a general-
