A comparator is also a device used in manufacturing to check critical dimensions.— Preceding unsigned comment added by 70.18.44.136 ( talk) 23:25, 27 March 2005 (UTC)
This article needs grammatical work....mety— Preceding undated comment added by 66.251.53.12 ( talk) 16:57, 23 June 2006 (UTC)
Generally, a manufacturing comparator is properly called a optical comparator, the CNC ruby touch type comparators are called a CMM.

Digital comparators are two types
1)Identity comparators
2)Magnitude comparators
Identity comparators show only whether two inputs are equal where as Magnitude comparators indicate which input is smaller or larger.
Digital comparators differ in terms of
•Supply voltage
•Number of bits
•Propagation delay
•Operating current
•Operating temperature

I took out two recently added sections with the strangely capitalized "OP Amplifier" in their headings. These seemed to be partly copied (and [1]) from the cited source and partly mangled beyond interpretability; presumably new editor User:Smurfettekla is the same as the anon who added the first one. Hopefully he'll explain his intentions here so we can fix it. Dicklyon ( talk) 05:08, 30 March 2009 (UTC)
Now as User:Berrinkursun, more uninterpretable stuff from the same book. I'm taking it out. If anyone wants to fix it, feel free. Dicklyon ( talk) 02:47, 31 March 2009 (UTC)
I'm taking a class on circuits and we're learning about op-amp comparators, including those with resistors that create hysteresis. This topic is not covered here.

I found that the links on this page were dead since they linked to the old National Semiconductor datasheets. I updated them to the datasheet on the Texas Instruments website. Ksumatrob ( talk) 05:04, 2 July 2014 (UTC)
Multicomparator is not mentioned (and shouldn't here? or?). See: 128-bit: " multicomparator". comp.arch ( talk) 10:10, 22 August 2014 (UTC)
Near "using an operational amplifier as a comparator presents several disadvantages":
I think it is missing an item in the list - phase reversal will prevent usage of some operational amplifiers as comparators.
Source for phase reversal, e.g.

Can the article be edited to include the name (if any) for a comparator that compares a state (e.g., a voltage) at different times, rather than, say, comparing instantaneous voltages at two different nodes? 38.67.192.226 ( talk) 23:28, 12 May 2017 (UTC)

In the section "Op-amp voltage comparator", the article references a "Figure 4", "Fig 5." and "the illustration" which either do exist on the page or are not properly labelled. — Preceding unsigned comment added by 174.6.253.121 ( talk) 15:17, 26 July 2018 (UTC)

"In practice, this circuit can be improved by incorporating a hysteresis voltage range to reduce its sensitivity to noise. The circuit shown in Figure 1, for example, will provide stable operation even when the Vin signal is somewhat noisy." Em3rgent0rdr ( talk) 08:16, 21 March 2022 (UTC)
