Abstract
Analog-to-digital and digital-to-analog converters are described which have internal reference voltage generators. These voltage generators include circuitry which senses the magnitude of the power supply voltage applied to the chip. The internal reference voltage generators then select one of two internal reference voltages as a reference voltage for the conversion operations depending on the magnitude of the power supply voltage.
