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 output swing also includes ground when ope-rating 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 micr-opower applications. The minimal voltage and current requirements of the OP290 suit it for battery- and solarowered applications, such as portable instruments, remote sensors, and satellites.
