OP490:  Low Voltage Micropower Quad Operational Amplifier

Product Details

The OP490 is a high performance micropower quad 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 OP490 to accommodate input signals down to ground in single-supply operation. The output swing of the OP490 also includes ground when operating from a single supply, enabling zero-in, zero-out operation.

The quad OP490 draws less than 20 μA of quiescent supply current per amplifier, but each amplifier is able to deliver over 5 mA of output current to a load. Input offset voltage is under 0.5 mV. Gain exceeds over 400,000 and CMR is better than 90 dB. A PSRR of under 5.6 μV/V minimizes offset voltage changes experienced in battery-powered systems.

The quad OP490 combines high performance with the space and cost savings of quad amplifiers. The minimal voltage and current requirements of the OP490 make it ideal for battery and solar-powered applications, such as portable instruments and remote sensors.
