Features, Applications

Precision, Low Power, Micropower Dual Operational Amplifier OP290

FEATURES Single-/Dual-Supply Operation, 18 V True Single-Supply Operation; Input and Output Voltage Ranges Include Ground Low Supply Current (Per Amplifier), 20 A Max High Output Drive, 5 mA Min Low Input Offset Voltage, 200 V Max High Open-Loop Gain, 700 V/mV Min Outstanding PSRR, 5.6 V/V Max Industry Standard 8-Lead Dual Pinout Available in Die Form GENERAL DESCRIPTION

The is a high performance micropower dual op amp that operates from a single supply V or from dual supplies 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 output swing also includes ground when operating from a single supply, enabling "zero-in, zero-out" operation. The OP290 draws less than A of quiescent supply current per amplifier, while able to deliver over mA of output current to a load. Input offset voltage is below 200 V 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.
