1°C. Use Figure 3 to estimate the temperature error
with respect to the MAX6666 packages.
Low-Voltage Logic
Use the MAX6667 open-drain output to drive low-volt-
age devices. As shown in Figure 4, connect a pullup
resistor from the low-voltage logic supply to the
MAX6667 output. Limit the resistor’s current to about
1mA, thus maintaining an output low logic level of less
than 200mV.
