NOTES:
3. Test Level: A. Production Tested; B. Typical or Guaranteed Limit Based on Characterization; C. Design Typical for Information Only.
4. The typical use for these amplifiers is in multiplexed configurations, where one amplifier (hostile channel) is enabled, and the passive channel
is disabled. The crosstalk data specified is tested in this manner, with the input signal applied to the hostile channel, while monitoring the output
of the passive channel. Crosstalk performance with both the hostile and passive channels enabled is typically -63dB at 5MHz, and -58dB at
10MHz.
5. Undershoot dominates for output signal swings below GND (e.g., 0.5VP-P), yielding a higher overshoot limit compared to the
VOUT = 0V to 0.5V condition. See the “Application Information“ section for details.
6. See Typical Performance Curves for more information.
7. Slew rates are asymmetrical if the output swings below GND (e.g., a bipolar signal). Positive unipolar output signals have symmetric positive
and negative slew rates comparable to the +SR specification. See the “Application Information” section, and the pulse response graphs for
details.
