When limiting the maximum input capacitance to 35 pF and the minimum operating
temperature to −20 °C then the minimum operating voltage can be reduced to 2.8 V. The
main limitation when lowering the supply voltage is a reduction in the range of the V
voltage, which is specified from 0.6 V to V
is equivalent to reducing the input capacitance range. Additionally, V
