CXD1175AM/AP
8-bit 20MSPS Video A/D Converter (CMOS)
Description
The CXD1175A is an 8-bit CMOS A/D converter
for video use. The adoption of a 2-step parallel
system achieves low consumption at a maximum
conversion speed of 20MSPS minimum, 35MSPS
typical.

∗1 The offset voltage EOB is a potential difference between VRB and a point of position where the voltage
drops equivalent to 1/2 LSB of the voltage when the output data changes from “00000000” to “00000001”.
EOT is a potential difference between VRT and a potential of point where the voltage rises equivalent to
1/2LSB of the voltage when the output data changes from “11111111” to “11111110”.
