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 µV/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.
