With wide bandwidth, 62 dBc Worst Harmonic 20 MHz low distortion, and low power, this device is ideal as a general- Single Supply Operation purpose amplifier. It also can be used to replace high speed Fully Specified for 5 V Supply amplifiers consuming more power. The AD8011 is a current feed- back amplifier and features gain flatness of 0.1 dB to 25 MHz APPLICATIONS while offering differential gain and phase error of 0.02% and 0.06 Power Sensitive, High Speed Systems on a single 5 V supply. This makes the AD8011 ideal for profes- Video Switchers sional video electronics such as cameras, video switchers, or any Distribution Amplifiers high speed portable equipment. Additionally, the AD8011s low A-to-D Driver distortion and fast settling make it ideal for buffering high speed Professional Cameras 8-, 10-, and 12-bit A-to-D converters. CCD Imaging Systems Ultrasound Equipment (Multichannel) The AD8011 offers very low power of 1 mA maximum and can run on single 5 V to 12 V supplies. All this is offered in a small 8-lead PDIP or 8-lead SOIC package. These features fit well with 5 portable and battery-powered applications where size and power G = +2 are critical. 4 R = 1k F V = +5V OR 5V S The AD8011 is available in the industrial temperature range of 3 V = 200mV p-p OUT 40C to +85C. 2 1 40 0 G = +2 THIRD 1 R = 150 L 2 3 60 SECOND R = 150 L 4 5 1 10 100 500 FREQUENCY (MHz) THIRD 80 R =1k L Figure 1.
