Abstract

PURPOSE: To constitute inexpensively an A/D converting circuit having a function of over range detection by applying logical operation to a digital output of an A/D converter having no over range detecting function so as to obtain an over range signal thereby using the A/D converter without over range detection function.
CONSTITUTION: An overflow detection circuit 7 of AND circuit constitution detecting that the level of all output bits of each output bit of an A/D converter 5 are at high level and an underflow detection circuit 8 of AND circuit constitution detecting that they are all at low level are provided. Then outputs of both the detection circuits are ORed to generate an over range output from an over range output terminal 9, allowing to constitute the inexpensive circuit only with simple logical circuits only.
