advice for max44000?

hello,

I have achieved a proximity sensor circuit with

the tsop4838 ir sensor. However, I just ran into this part:

Now, I would like to know if anyone used the max44000

part for proximity sensing ???

And can anyone tell me what is the maximum distance

that the max44000 part can detect an object. In the spec

it says 1.5 uw/cms LSB??? From that info, how can one deduct it’s

maximum proximity capability???

Also, what would be the benefits of using

the tsop solution versus the max44000 solution.

It seems to me that the max44000 is much simpler

to connect given that it takes care of all the

signal bursts for you!!!

a little undecided,I would really need another

point of view!!!

All feedback is sincerely appreciated!

I don’t have an answer for you, but you’ll probably find more help over in the technical side of the forums. The folks who can actually help help probably won’t see your post here.

Thanks CS Paul…

I don’t think I am going to switch… as the costs

are very comparable between what I am doing

and what the max44000 is doing given that they too

have to use extra hardware if they want to have

a greater detection range than 30cm!

thanks for replying!
