Analog Devices OP490
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 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.| Part No. | OP490 |

GENERAL DESCRIPTION
Low Voltage Micropower Quad Operational Amplifier OP490 PIN CONNECTION 14-Pin Hermetic DIP (Y-Suffix) 14-Pin Plastic DIP (P-Suffix) OUT A –IN A +IN A 1 2 3 14 OUT D 13 –IN D 12 +IN D 11 V– 10 +IN C 9 –IN C 8 OUT C V+ 4 +IN B 5 –IN B 6 OUT B 7 Input voltage range includes the negative rail allowing the OP490 to accommodate input signals down to ground in single-supply operation. 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.
