GENERAL DESCRIPTION  
The OP290 is a high performance micropower dual 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 OP290 to accommodate input signals  
down to ground in single-supply operation. The OP290 output  
swing also includes ground when operating from a single  
supply, enabling zero-in, zero-out operation.  
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 OP290 bring  
precision performance to micropower applications. The  
minimal voltage and current requirements of the OP290 suit it  
for battery- and solar-powered applications, such as portable  
instruments, remote sensors, and satellites. For a single op amp,  
see the OP90; for a quad, see the OP490.  
The OP290 draws less than 20 μA of quiescent supply current  
per amplifier, while being able to deliver over 5 mA of output  
current to a load. Input offset voltage is below 200 μV, eliminat-  
ing the need for external nulling. Gain exceeds 700,000 and
