Because digital systems often have only a single-polarity power supply, a common problem becomes translating an opposite-polarity pulse train into a positive-or negative-pulse output. Here are some ...

Voltage comparators began appearing in single-chip microcontrollers (MCUs) in the late 1990s. At the time, the change was viewed as a simple cost reduction. Comparators required less silicon, while ...

A comparator is an electronic component that outputs different voltage results at the output by comparing the magnitude of the current or voltage at the two inputs. This article describes the ...

(Editor's Note: There are links to the previous parts of this series at the end, below the author's biography.) Determining if one voltage is greater than or less than another voltage is the job for a ...

An ultra low power voltage comparator that is said to consume one third of current for the same response time compared to competing devices has been announced by STMicroelectronics. The new TS33 ...

The LMV393 and LMV339 devices are low-voltage (2.7 V to 5.5 V) versions of the dual and quad comparators, LM393 and LM339, which operate from 5 V to 30 V. The LMV331 is the single-comparator ...
