SA58602
GENERAL DESCRIPTION
The SA58602 is a low voltage, high precision dual operational
amplifier. The input offset voltage is typically 100
µV
with a very low
temperature drift of
±
1
µV/°C.
The SA58602 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
SA58602 is ideal for battery powered applications. It is excellent for
precision amplifiers in portable instrumentation equipment used for
test and measurement, medical monitors and diagnostics, and
remote meters and sensors.
