GENERAL DESCRIPTION

The SA58603 is comprised of a low voltage, high precision dual operational amplifier, a comparator, and a reference voltage source. The input offset voltage is typically 100 μV with a very low temperature drift of ±1 μV/°C. The SA58603 supply current is typically 100 μA per amplifier and it operates from 1.8 V to 6 V single supply.
