... Note 2: Does not include current into the external-feedback network. Note 3: Over operating supply-voltage range. Note 4: Specification applies to MAX4180/MAX4181/MAX4183 and MAX4185. Note 5: The AC specifications shown are not measured in a production test environment. The minimum AC specifications given are based on the combination of worst-case design simulations along with a sample characterization of units. These minimum specifications are for design guidance only and are not intended to guarantee AC performance (see AC Testing/Perform- ance) ...

... This feature, combined with fast settling time, makes these devices suitable for buffering high-speed analog-to-digital converters (ADCs). The MAX4180/MAX4181/MAX4183/MAX4185 have a low-power shutdown mode that is activated by driving the amplifiers’ SHDN input low. Placing them in shut- down reduces quiescent supply current to 135µA (typ) and places amplifier outputs in a high-impedance state ...

Component Side 16 ______________________________________________________________________________________ Maxim’s High-Speed Evaluation Board Figures 2 and 3 show layouts of Maxim’s high-speed single SOT23 and SO evaluation boards. These boards were developed using the techniques described above. The smallest available surface-mount resistors were used for feedback and back-termination to minimize their distance from the part, reducing the capacitance associated with longer lead lengths ...
