... 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 AD817 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 ...

... C L 1000pF INPUT CONSIDERATIONS An input protection resistor (R cuits where the input to the AD817 will be subjected to tran- sient or continuous overload voltages exceeding the +6 V maximum differential limit. This resistor provides protection for 100pF the input transistors by limiting their maximum base current. For high performance circuits recommended that a “bal- ancing” ...

... OFFSET NULLING The input offset voltage of the AD817 is inherently very low. However, if additional nulling is required, the circuit shown in Figure 32 can be used. The null range of the AD817 in this con- figuration is 15 mV. AD817 SETTLING TIME Settling time is comprised primarily of two regions. The first is the slew time in which the amplifier is overdriven, where the output voltage rate of change is at its maximum ...

... ADC—a common problem with buffers operating at higher supply voltages. SINGLE SUPPLY OPERATION Another exciting feature of the AD817 is its ability to perform well in a single supply configuration. The AD817 is ideally suited for applications that require low power dissipation and high output current and those which need to drive large capaci- tive loads, such as high speed buffering and instrumentation ...

... AD817 HIGH SPEED DAC BUFFER The wide bandwidth and fast settling time of the AD817 make it a very good output buffer for high speed current output D/A converters like the AD668. As shown in Figure 38, the op amp establishes a summing node at ground for the DAC output. The output voltage is determined by the amplifier’ ...
