Photoelectric conversion apparatus and equipment having ad conversion circuits

A photoelectric conversion apparatus comprising:

• a plurality of pixels arranged in a form of a plurality of rows and a plurality of columns;
• a plurality of output lines, arranged in one to at least one correspondence between the plurality of columns and the plurality of output lines, each configured to receive an analog signal output from a corresponding pixel of the plurality of pixels;
• a scanning circuit configured to supply a control signal to output the analog signal to the plurality of output lines;
• and
• a first analog-to-digital (AD) conversion circuit and a second AD conversion circuit configured to perform AD conversion on the analog signal,
• wherein the scanning circuit is configured to perform
• a first scanning in which the control signal is sequentially supplied to a first pixel group in order of the plurality of rows, the first pixel group including two or more pixels that are of the plurality of pixels and arranged in two or more rows, and
• a second scanning in which the control signal is sequentially supplied to a second pixel group in order of the plurality of rows, the second pixel group including other two or more pixels that are of the plurality of pixels and arranged in two or more rows,
• wherein a range from a start row to an end row of the first scanning includes at least a part of a range from a start row to an end row of the second scanning,
• wherein a first analog signal group output from the first pixel group in the first scanning is input to the first AD conversion circuit and the second AD conversion circuit,
• wherein a second analog signal group output from the second pixel group in the second scanning is input to the first AD conversion circuit and the second AD conversion circuit,
• wherein the first AD conversion circuit and the second AD conversion circuit each include a comparator to which the first analog signal group is not input in the first scanning and the second analog signal group is input in the second scanning,
• wherein, in a longitudinal direction of the plurality of output lines, the first AD conversion circuit is disposed on one end side of the plurality of output lines, and
• wherein, in the longitudinal direction of the plurality of output lines, the second AD conversion circuit is disposed on an other end side of the plurality of output lines.
