com INTEGRATED CIRCUITS SA58603 High precision operational amplifier, comparator, and voltage reference Product data Supersedes data of 2001 Oct 03 2002 Nov 13 Philips Semiconductors Philips Semiconductors Product data High precision operational amplifier, comparator, and voltage reference SA58603 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.
Having single power supply capability, low current consumption, low offset voltage, low input offset current and low input bias current, the SA58603 is ideal for battery-powered applications and amplification of very small signals.
It is excellent for precision amplifiers in gas burners and gas pilot water heaters which use thermal couple heat sensors.
