Analog Devices OP90
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.| Part No. | OP90 |

GENERAL DESCRIPTION
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 PIN CONNECTIONS 8-Lead Epoxy Mini-DIP (P-Suffix) 8-Lead SO (S-Suffix) VOS NULL 1 –IN 2 8 NC 7 V+ +IN 3 V– 4 6 OUT 5 VOS NULL NC = NO CONNECT 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.
