A photoelectric conversion device includes analog signal output units (11, 20-n) including pixels (11) and configured to output analog signals based on pixels, and signal processing units (30-n, 31, 40-n). Each signal processing unit is provided correspondingly to one of the analog signal output units and including a gain application unit (GA) configured to apply a gain to an analog signal by using only passive elements and an AD conversion unit. In the gain application unit, a portion that contributes to application of a gain is constituted only of passive elements. The gain application unit selectively outputs a first amplified signal obtained by applying a first gain to the analog signal or a second amplified signal obtained by applying a second gain to the analog signal smaller than the first gain. The AD conversion unit converts, from analog to digital, the first or second amplified signal. |
