An interpolation circuit includes: a generation circuit configured to generate interpolated data based on a plurality of pieces of input data in time sequence; a first analog digital converter configured to convert first interpolated data at a data point of the interpolated data into first digital data; and a second analog digital converter configured to convert second interpolated data at a change point into second digital data of the interpolated data, a second number of quantization bits of the second analog digital converter being smaller than a first number of quantization bits of the first analog digital converter.
