Abstract
A radiation imaging apparatus is provided. The apparatus includes a pixel array in which pixels are arranged, and a readout circuit configured to read out the signal from the pixel array, and configured to operate in a plurality of modes including a first mode and a second mode in which a time between imagings is longer than in the first mode. The readout circuit includes an integration amplifier configured to amplify the signal read out from the pixel array, and a sample and hold circuit configured to hold the signal amplified by the integration amplifier, the integration amplifier is configured to be able to switch a current driving capability for driving an input node of the sample and hold circuit, and the current driving capability in the first mode is higher than the current driving capability in the second mode.
