GENERAL DESCRIPTION

The OP490 is a high-performance micropower quad op amp
that operates from a single supply of 1.6 V to 36 V or from
dual supplies of ± 0.8 V to ± 18 V. Input voltage range includes
the negative rail allowing the OP490 to accommodate input
signals down to ground in single-supply operation. The
OP490’s output swing also includes ground when operating
from a single supply, enabling “zero-in, zero-out” operation.

The quad OP490 draws less than 20 mA of quiescent supply
current per amplifier, but each amplifier is able to deliver
over 5 mA of output current to a load. Input offset voltage is
under 0.5 mV with offset drift below 5 mV/∞C over the military
temperature range. Gain exceeds over 700,000 and CMR is
better than 100 dB. A PSRR of under 5.6 mV/V minimizes
offset voltage changes experienced in battery-powered systems.

The quad OP490 combines high performance with the space
and cost savings of quad amplifiers. The minimal voltage and
current requirements of the OP490 make it ideal for battery­and solar-powered applications, such as portable instruments
and remote sensors.

CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the OP490 features proprietary ESD protection circuitry, permanent damage may occur on devices
subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
