Is this : https://www.jaycar.com.au/medias/sys_master/images/images/9525094088734/ZL3741-dataSheetMain.pdf
a replacement for an INA122P in this loadcell amplifier circuit : https://www.instructables.com/Racing-Sim-brake-pedal-load-cell-interface/

If so can someone confirm what pins correspond to the INA122P as they are slightly different layout I think ?

Thanks
Ken

 

hi n,
The 741 is a very old OPA, it is not a replacement for the INA122P

Thanks
I need one ASAP and the 741 is available but the INA122 seems to be hard to come by here in Australia
Looks like I am in for a wait

 

hi,
Have you checked eBay.

Thanks people - I had ordered one that was supposedly in stock in Aus for immediate shipping.
4 weeks later they tell me it is on backorder and will be another 8 weeks. This would have cost me $8
DIgi-Key want $40 and it has to come from the US - so another 2-4weeks for post.
RS say it is in Global Stock for 7 day delivery - which with Covid restrictions will probably be 2-4weeks also and they want $30
eBay ones aren't genuine TI and coming from China so a minimum of 4 weeks and probably closer to 8
