PURPOSE:To correct an analog signal at low cost and at high speed with simple configuration by connecting a detected digital output to an address input and outputting function corrected data from a read only memory(ROM). CONSTITUTION:The digital output line of an A/D converter 2 is connected to the address input line of a ROM 3 and inputted to terminals A0-A7 of the memory 3. The data output of this memory 3 is provided with a data area corresponding to address input bits and when the patterns of the terminals A0-A7 are decided, the digital output is enabled at high speed without performing any operation processing. Then, the output of the memory 3 is converted to the analog signal by a D/A converter 4 and can be outputted through an analog buffer 5. Thus, the analog signal is corrected at low cost and at high speed with simple circuit configuration. |
