... MHz) voltage feedback amplifiers with an exception- ally low quiescent current of 1.0 mA/amplifier typical (1.5 mA max). The AD8038 single amplifier in the SOIC-8 package has a dis- able feature. Despite being low power and low cost, the amplifier provides excellent overall performance. Additionally, it offers a high slew rate of 425 V/µ ...

... 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 AD8038/AD8039 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 ...

... LAYOUT, GROUNDING, AND BYPASSING CONSIDERATIONS Disable The AD8038 in the SOIC-8 package provides a disable feature. This feature disables the input from the output (see TPC 37 for input-output isolation) and reduces the quiescent current from typically 0.2 mA. When the DISABLE node is pulled below 4 ...

... The AD8038 can be used to make an effective low-pass active filter that consumes one-fifth of the power consumed by an active filter made from an op amp. Figure 4 shows a circuit that uses an AD8038 to create a single ± 2.5 V supply, three-pole Sallen-Key filter. This circuit uses a single RC pole in front of a standard two-pole active section. ...
