Abstract
A circuit disclosed maintains ratiometric analog inputs to an integrated circuit using a network of resistors, some of which are external to the integrated circuit and some of which are internal to the integrated circuit, reducing expense. The analog inputs maintain a fixed ratio during fluctuations in supply voltage and fluctuations in temperature.
