OP290GPZ

OP290 is a high performance micropower dual op-amp. Input voltage range includes the negative rail allowing the OP290 to accommodate input signals down to ground in single-supply operation. The OP290 output swing also includes ground when operating from a single supply, enabling zero-in, zero-out operation. 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.
