Hi there,
I would like to know what's the response time of the ALERT function after any of the user-defined threshold has been exceeded.
From Figure 28 and 29 in the datasheet, it seems that it has something to do with the Conversion Time.
Is this the only way to change the response time? If yes, what's the relationship between the two?
Could you please comment? Thank you!
Best regards,
Roy Hsu
Roy,
The tCT of these two plots is reversed. Figure 28 should be tCT = 140uS, and figure 29 should be tCT = 1.1mS.
Also, these plots show one instance of the edge falling, when in fact it can be a range. Figures 39 and 40 of the sister part INA260 show a better representation of the output, in my opinion.
Roy,
Basically the ALERT condition is evaluated after every sample, as defined by the conversion time, but not as defined by the averaging (meaning that even during averaging, you could have an ALERT signal). Figure 19 in the INA226 data sheet shows what I mean by this:
Nothing else comes to mind to note about using this ALERT feature.
