Precision, Low Voltage Micropower Operational Amplifier
The OP90 is a high performance, micropower 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. The input voltage range includes the negative rail allowing the OP90 to accommodate input signals down to ground in a single-supply operation. The OP90’s output swing also includes a ground when operating from a single-supply, enabling “zero-in, zero-out” operation.
The OP90 draws less than 20 μA of quiescent supply current, while able to deliver over 5 mA of output current to a load. The input offset voltage is below 150 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 OP90 bring precision performance to micropower applications. The minimal voltage and current requirements of the OP90 suit it for battery and solar powered applications, such as portable instruments, remote sensors, and satellites.
