Comparators feature micropower operation under all conditions

Jim Williams

Abstract

A series of comparators which feature micropower operation under all conditions is described.

micropower comparator

LTC1440 series

Some micropower comparators have operating modes that allow excessive current drain. In particular, poorly designed devices can conduct large transient currents during switching. Such behavior causes dramatically increased power drain with rising frequency, or when the inputs are nearly balanced, as in battery monitoring applications.

Figure 483.1 shows a popular micropower comparator’s current consumption during switching. Trace A is the input pulse, trace B is the output response and trace ...
