... 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 AD8033/AD8034 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 ...

... Input Impedance The input capacitance of the AD8033/AD8034 will form a pole with the feedback network, resulting in peaking and ringing in the overall response. The equivalent impedance of the feedback network should be kept small enough to ensure that the parasitic pole falls well beyond the – ...

... APPLICATIONS High Speed Peak Detector The low input bias current and high bandwidth of the AD8033/ AD8034 make the parts ideal for a fast settling, low leakage peak detector. The classic fast-low leakage topology with a diode in the output is limited to 1.4 V p-p max in the case of the AD8033/AD8034 because of the protection diodes across the inputs, as depicted in Figure 4 ...

... AD8033/AD8034 Using the AD8033/AD8034, a unity gain peak detector can be constructed that will capture a 300 ns pulse while still taking advantage of the AD8033/AD8034’s low input bias current and wide common-mode input range, as shown in Figure 5. Using two amplifiers, the difference between the peak and the current input level is forced across R2 instead of either amplifier’ ...

... The common-mode input capacitance should be considered in the component selection. Filter cutoff frequencies can be increased beyond 1 MHz using the AD8033/AD8034, but limited open-loop gain and input impedance begin to interfere with the higher Q stages. This can cause early roll-off of the overall response. Additionally, the stop-band attenuation will decrease with decreasing open-loop gain ...
