ha17741

I've bought a ha17741 op amp,but what the circuit I am about to buildup require a ua741.Can ha17741 be used to buildup the circuit instead of ua741?
And I found that the circuit schematic connect the ua741's v- to ground,and v+ to 9v power supply.I don't know if it's correct?
I'm a newbie.
Thank you !

Yes, HA17741 is pin compatible to uA741.

It depends on the input range of op amp in your design. If V+ is connected to 9V and V- is connected to GND, the input range of the op amp should be (slightly) higher than 0V and (few volts) lower than +9V because uA741 is not an rail-to-rail input/output op amp.
 

op amp 741 ha17741

Thank you,I've looked up the datasheets of the two 741s.
Their most parameters and electric characteristics are same.
I asked this question because there are some difference between the datesheets of the 741.Such as DC gain,ha17741 is 106db, ua741 is 200v/mv,they use different unit,and I don't know what kind of circumstance under which the gain value get.
I think since they are all 741,the difference must be little.So they must be compatible.
Thank you again!
