GENERAL DESCRIPTION  
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.ꢀ V to 1ꢀ V. The input voltage range includes  
the negative rail allowing the OP490 to accommodate input  
signals down to ground in single-supply operation. The output  
swing of the OP490 also includes ground when operating from  
a single supply, enabling zero-in, zero-out operation.  
0.5 mV. Gain exceeds over 400,000 and CMR is better than  
90 dB. A PSRR of under 5.6 μV/V minimizes offset voltage  
changes experienced in battery-powered systems.  
The quad OP490 combines high performance with the space  
and cost savings of quad amplifiers. The minimal voltage and  
current requirements of the OP490 make it ideal for battery and  
solar-powered applications, such as portable instruments and  
remote sensors.  
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. Input offset voltage is under  
Rev. E
