ASI183 Manual
12
6.6 Analog to Digital Converter (ADC)
The ASI183 camera records in 12bit ADC and 10bit ADC. You can image at a faster fps rate
if you choose to use 10bit ADC (high speed mode). This camera also supports ROI (region of
interest) shooting, and this smaller ROI has faster fps. You can uncheck “high speed” and choose
8bit output on software to enable 10bit ADC output, otherwise this camera will use 12bit ADC.
Here is the maximum speed of ASI183 running at 10bit ADC or 12bit ADC at 8bit mode.

6.7 Binning
The ASI183 camera supports hardware bin2 and software bin2, bin3 and bin4 mode.
Hardware binning is supported by sensor but is done in digital domain like software binning and
use 10bit ADC. The only advantage of hardware binning is faster fps. We recommend customer to
use software binning if you don’t care speed.
6.8 DDR Buffer
The ASI183 Pro camera includes a 256MB DDR3 memory buffer to help improve data
transfer reliability. Additionally, the use of a memory buffer minimizes amp-glow, which is caused
by the slow transfer speeds when the camera is used with a USB 2.0 port. DDR memory buffer is
the main difference between ASI “Cool” and “Pro” cameras.
