This typically can be detected as this type of capacitive coupling increases at higher frequencies. (6) Positive excursions of input voltage may exceed the power supply level. As long as the other input voltage remains within the common- mode range, the comparator will provide a proper output state. The input voltage to the op amp should not exceed the power supply level. The input voltage state must not be less than −0.3V (or 0.3V below the magnitude of the negative power supply, if used) on either amplifier. (7) The response time specified is for a 100 mV input step with 5 mV overdrive. For larger overdrive signals 300 ns can be obtained. 4 Submit Documentation Feedback Copyright © 1998–2013, Texas Instruments Incorporated Product Folder Links: LM392-N |
