Abstract
PURPOSE:To eliminate the need for a control terminal by selecting a reference voltage on the basis of the level of the reference voltage supplied from an external terminal. CONSTITUTION:An external reference voltage VEXT supplied to an external reference voltage input terminal 1 is discriminated on the basis of an input threshold voltage value VTH determined by an inverter circuit 21 to output lines 3 and 4 binary signals which have mutually complementary logical levels and switch analog switches 6 and 7 complementarily. When the external reference voltage vEXT is lower than the threshold voltage value VTH, a voltage having a value VINT is applied from an internal reference voltage source 5 to an output terminal 8. When not, the analog switch 6 is closed, so the external reference voltage source 5 to an output terminal 8. When not, the analog switch 6 is closed, so the external reference voltage is developed at the output terminal 8.
