SA58603D中文资料飞利浦数据手册PDF规格书

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.
