Zero-Crossing Detector
Figure 3 shows a zero-crossing detector application.
The MAX987’s inverting input is connected to ground,
and its noninverting input is connected to a 100mVp-p
signal source. As the signal at the noninverting input
crosses 0V, the comparator’s output changes state.
Logic-Level Translator
Figure 4 shows an application that converts 5V logic lev-
els to 3V logic levels. The MAX988 is powered by the +5V
supply voltage, and the pull-up resistor for the MAX988’s
open-drain output is connected to the +3V supply volt-
age. This configuration allows the full 5V logic swing with-
out creating overvoltage on the 3V logic inputs. For 3V to
5V logic-level translation, simply connect the +3V supply
to VCC and the +5V supply to the pull-up resistor.
