Single/Dual Supply Operation: 1.6 V to 36 V, /H115500.8 V to /H1155018 V True Single-Supply Operation; Input and Output Voltage Ranges Include Ground Low Supply Current: 20 /H9262A Max High Output Drive: 5 mA Min Low Input Offset Voltage: 150 /H9262V Max High Open-Loop Gain: 700 V/mV Min Outstanding PSRR: 5.6 /H9262V/V Max Standard 741 Pinout with Nulling to V– GENERAL DESCRIPTION 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 *ELECTRONICALL Y ADJUSTED ON CHIP FOR MINIMUM OFFSET VOL T AGE NULL NULL –IN +IN OUTPUT Figure 1.

APPLICATION INFORMATION
Battery-Powered Applications The OP90 can be operated on a minimum supply voltage of 1.6 V, or with dual supplies ± 0.8 V, and draws only 14 pA of supply current. In many battery-powered circuits, the OP90 can be continuously operated for thousands of hours before requiring battery replacement, reducing equipment down time and operating cost. High-performance portable equipment and instruments frequently use lithium cells because of their long shelf-life, light weight, and high-energy density relative to older primary cells. Most lithium cells have a nominal output voltage of 3 V and are noted for a flat discharge characteristic. The low-supply voltage requirement of the OP90, combined with the flat discharge characteristic of the lithium cell, indicates that the OP90 can be operated over the entire useful life of the cell. Figure 1 shows the typical dis- charge characteristic of a 1Ah lithium cell powering an OP90 which, in turn, is driving full output swing into a 100 k Ω load.
