KM 03:38 PM Support: RE: top and bottom half sensor temp

Ok great thanks! Just wanted to double check.

MW 03:16 PM Support: RE: top and bottom half sensor temp

Hi Kyle,
This is why we use an external thermistor attached to the sensor for temperature reporting. We have observed quite a bit of variance in the VPTAT voltages from chip to chip wrt temperature.
Each half of the 2521 sensor re... Michael Williamson

KM 03:10 PM Support: top and bottom half sensor temp

I have noticed that there is a big temp difference between the top and bottom half of the sensor.
Example:
Vptat_Top: 2.12863V : 35.3651C
Vptat_Bot: 2.16838V : 44.065C
I took a look at the sensor with a thermal camera and di... Kyle McKinney

KM 10:41 AM Support: RE: High/Low gain mode using 8bpp-12bpp

Mike, is there a similar bias in the 8bit and 12bit modes?
If so what is it?
Does 12bit pack into 11bits in those modes?

KM 01:11 PM Support: RE: High/Low gain mode issue using 16bpp

Ah, ok well that explains it! No problem, just good to know what is happening.
Thanks.

MW 12:50 PM Support: RE: High/Low gain mode issue using 16bpp

There is a 20 count bias in the data. It's a bug in the mode you are using.
During calibrated high/low gain blending (normal operation), there is a 20 count bias added (digitally) to each of the channels prior to the blending.

KM 12:38 PM Support: RE: High/Low gain mode issue using 16bpp

I use MATLAB to look at and process the data. Knowing that the data is packed into the lower 11 helps answers my question.
Using only 11bits should produce a maximum pixel value of 2047 but I am getting pixel values that peak at 2067. ... Kyle McKinney
