Responding to: ???'s previous message
The system is a Kiln Scanner,The kiln length is 67 meter,and the scanner is about 30 meter away,the scanner must scan the surface of the kiln 20 times per second,and in every scan 1500 samples must be captured (100 degree field of view) so we must have 1500*20*360/100 samples per second,

Moreover, from what I can determine from a translation of the datasheet you linked, these sensors have timeconstants in the hundreds of microseconds, so 100k samples/second is overkill, to say the least.



I have translated the datasheet and didn't see what you said,
I have Received 40 Khz signal with this sensor from Ir Remote Control with less than 5 usecond rise and fall times,
