... MHz while offering differential gain and phase error of 0.02% and 0.06° single 5 V supply. This makes the AD8011 ideal for profes- sional video electronics such as cameras, video switchers, or any high speed portable equipment. Additionally, the AD8011’s low distortion and fast settling make it ideal for buffering high speed 8-, 10-, and 12-bit A-to-D converters ...

... ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD8011 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality ...

... N Q2 INP REV. C Overall, when high external load drive and low ac distortion is a requirement, a twin gain stage integrating amplifier like the AD8011 will provide superior results for lower power over the traditional single-stage complementary devices. In addition, being a CF )/(distortion power)], amplifier, closed-loop BW variations versus external gain variations (varying RN) will be much lower compared amp, where the BW varies inversely with gain ...

... Q4 output conductances are assumed zero.) These A assumptions result in actual versus model open-loop voltage gain and associated input referred error terms being less accurate for G low gain (G) noninverting operation at the frequencies below the R G open-loop pole of the AD8011. This is primarily a result of the + + input signal (V O ...

... FREQUENCY (Hz) Figure 9. Open-Loop Transimpedance Gain Note that the ac open-loop plots in Figures 8, 9, and 10 are based on the full SPICE AD8011 simulations and do not include external parasitics (see equations below). Nevertheless, these ac loop equations still provide a good approximation to simulated and actual performance up to the CLBW of the amplifier. Typi- cally – ...

... Figure 12) the computed BW, using the previous V (s) equation, typically will O be lower than the AD8011’s measured small signal BW. See data sheet Bode plots. With only internal parasitics included, the BW is extended due to the complex pole pairs created primarily versus the single-pole assumption shown above ...

... The AD8011 is well positioned for driving this new class of A/D converters. Figure 14 shows a circuit that uses an AD8011 to drive an AD876, a single-supply, 10-bit, 20 MSPS A/D converter that requires only 140 mW. Using the AD8011 for level shifting and driving, the A/D exhibits no degradation in performance compared to when it is driven from a signal generator ...
