OP290:  Low Voltage Dual Precision, Micropower Op Amp

Product Details


Newer Alternatives: NEW DESIGNS consider the RRIO ADA4096-2 with higher speed, lower noise and lower offset.

The OP290 is a high performance micropower dual op amp that operates from a single supply of +1.6V to +36V or from dual supplies of ±0.8V to ±18V. Input voltage range includes the negative rail allowing the OP290 to accomodate input signals down to ground in single supply operation. The OP290s output swing also includes ground when operating from a single supply, enabling zero-in, zero-out operation.

The OP290 draws less than 20µA of quiescent supply current per amplifier, while able to deliver over 5mA of output current to a load. Input offset voltage is below 200µV eliminating the need for external nulling. Gain exceeds 700,000 and common-mode rejection is better than 100dB. The power supply rejection ratio supply rejection ratio of under 5.6µV/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.
