... DIP packages will be marked with a “B” by pin 8. The “B” grade of the SOT23-5 will be marked with a “B” near pins 3 and 4. (3) The SOT23-5 is only available on a 7" tape and reel (e.g. ordering 250 pieces of “OPA642N-250” will get a single 250 piece tape and reel. Ordering 3000 pieces of “OPA642N-3k” will get a single 3000 piece tape and reel). Please refer to Appendix B of Burr-Brown IC Data Book for detailed Tape and Reel Mechanical information. The information provided herein is believed to be reliable ...

APPLICATIONS INFORMATION WIDEBAND VOLTAGE FEEDBACK OPERATION The OPA642’s combination of speed and dynamic range is easily achieved in a wide variety of application circuits, providing that simple principles of good design practice are observed. For example, good power supply decoupling, ...

DAC TRANSIMPEDANCE AMPLIFIER High frequency DDC DACs require a low distortion output amplifier to retain their SFDR performance into real-world loads. A single-ended output drive implementation is shown in Figure 4. In this circuit, only one side of the complemen- ...

In the inverting configuration, an additional design consid- eration must be noted. R becomes the input resistor and G therefore the load impedance to the driving source. If imped- ance matching is desired, R may be set equal to the ...

Socketing a high speed part like the OPA642 is not recommended. The additional lead length and pin-to-pin capacitance introduced by the socket can create an ex- tremely troublesome parasitic network which can make it almost impossible to achieve a ...
