Abstract

PURPOSE:To reduce a quantizing error by providing a plurality of input converters having different conversion rates for the same input signal, and lap writing conversion signals in a memory to convert a 12-bit code into a 16-bit code. CONSTITUTION:Input converters 10, 11 having different conversion rates for the same input signal I1 are provided. The outputs of the converters 10, 11 are converted through a multiplexer MXP13 and an analog/digital converter 14 to digital signals. Then, they are lap written in the same area of a memory RAM 16. Thus, since a 12-bit code is converted to a 16-bit code, A/D-converted 12-bit data can take a wide dynamic range equivalent to 16-bit data.
