... The comparators’ internal hysteresis ensures clean output switching, even with slow-moving input signals. For space-critical applications, the single MAX998 is available in a 6-pin SOT23 package, the dual MAX976 ® is available in an 8-pin µMAX package, and the quad MAX978 is available in a 16-pin QSOP package. ...

... Power-Up Delay Note 1: The MAX998EUT specifications are 100% tested at T teed by design, not production tested. Note 2: Inferred from CMRR test. Either input can be driven to the absolute maximum limit without false output inversion, as long as the other input is within the common-mode voltage range. Note defined as the mean of trip points ...

... The MAX998 features a low-power shutdown mode that places the output in a high-impedance state and reduces supply current to 1nA. Activate shutdown mode by driving SHDN low. The MAX976/MAX978/MAX998 comparator inputs have a common-mode voltage range of -0. _______________________________________________________________________________________ MAX976 TOC16 > V ...

... This tends to occur when the voltage on one input is equal to or very close to the voltage on the other input. The MAX976/MAX978/MAX998 have inter- nal hysteresis to counter parasitic effects and noise. The hysteresis in a comparator creates two trip points: one for the rising input voltage and one for the falling input voltage (Figure 1) ...

... When this voltage level crosses the voltage applied by the voltage divider to the inverting input, the output transitions. _______________________________________________________________________________________ CC The MAX976 is ideal for making a window detector (undervoltage/overvoltage detector). The schematic shown in Figure 3 uses a MAX6120 reference and com- 0.1μF ponent values selected for a 2.0V undervoltage thresh- old and a 2 ...
