OP490GBC:  Low-Voltage Micropower Quad Operational Amplifier

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. Input voltage range includes the negative rail allowing the OP490 to accommodate input signals down to ground in single-supply operation. The OP490's output swing 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 with offset drift below 5 µV/°C over the military temperature range. Gain exceeds over 700,000 and CMR is better than 100 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 makes it ideal for battery and solar powered applications, such as portable instruments and remote sensors.
