SVIAAL/VI Precision Low Voltage Micropower Operational Amplifier General Description The OP90 is a precision bipolar micropower operational amplifier with flexible power supply capability. Both the input voltage range and output voltage swing of the OP90 include the negative rail, allowing ground- sensing operation when the part is driven froma single positive voltage supply. The OP90 will accept a single power supply voltage of any value in the range +1.6V to +36V. Alternatively, the amplifier can be operated from dual power supplies in the range of t0.8V to +18V. Unlike most other micropower operational amplifiers, the OP90 requires no external current setting resistor, and consumes less than 20uA of quiescent current, allowing operation from a lithium battery of greater than 10,000 hours. Even with this minimal current consumption, the amplifier can sink or source 5mA of current into the load. Every OP90 (A/E grade) is internally trimmed to guar- antee an input offset voltage of less than 150uV. This eliminates the need for external nulling in most appli- cations, although null pins are provided if required. The guaranteed minimum open loop gain of 700,000 together with power supply rejection ratio of 5.6uV/V and common-mode rejection ratio of 100dB allow the OP90 to be used in applications requiring low power operation together with precision performance.
