... 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 “OPA643N-250” will get a single 250 piece tape and reel. Ordering 3000 pieces of “OPA643N-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 TYPICAL APPLICATION AND CHARACTERIZATION CIRCUIT The OPA643’s combination of speed and dynamic range is easily achieved in a wide variety of application circuits, providing that simple guidelines common to all high speed amplifiers are observed. For example, good ...

This capacitor provides a low source impedance for the transient currents produced by the sampling process. Improved SFDR is obtained by adding the capacitor, whose value is often recommended in the converter data sheet. The external capacitor, in combination ...

This will increase the Q for the closed-loop poles, peaking up the frequency response and extending the bandwidth. A peaked frequency response will show overshoot and ringing in the pulse response as well as a higher integrated output noise. Operating ...

For the values shown in Figure 6, the F approximately 105MHz. This is less than that predicted by simply dividing the GBP product by NG network controls the bandwidth to a lower value while providing full slew rate and exceptional ...

This effect is due to the reduction in loop gain which accompanies an increase in signal gain. Finally, distortion grows as the fundamental frequency increases, due to the rolloff in loop ...

The total output noise voltage density can be computed as the square root of the sum of all squared output noise voltage contributors. Equation 1 shows the general form for the output noise voltage using the terms shown in Figure ...
