GENERAL DESCRIPTION

The OP290 is a high performance micropower dual 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 OP290 to accommodate input signals
down to ground in single-supply operation. The OP290’s out-
put swing also includes ground when operating from a single
supply, enabling “zero-in, zero-out” operation.
The OP290 draws less than 20 µA of quiescent supply current
per amplifier, while able to deliver over 5 mA of output current
to a load. Input offset voltage is below 200 µV eliminating the
need for external nulling. Gain exceeds 700,000 and common-mode
rejection is better than 100 dB. The power supply rejection ratio
of under 5.6 pV/V minimizes offset voltage changes experienced
in battery-powered systems. The low offset voltage and high gain
offered by the OP290 bring precision performance to micropower
applications. The minimal voltage and current requirements
of the OP290 suit it for battery- and solar-powered applications,
such as portable instruments, remote sensors, and satellites. For
a single op amp, see the OP90; for a quad, see the OP490.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the OP290 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.
