Replacement for Op2177

[shetty_18]

hii...

quick question...any one knows a replacement IC for OP2177 , with a single input supply of may be 3.3V, 5V or 12V.
These are the power supplies available on my board and i dont want to use any DC DC converter as well.

Or any website where i can find replacements.

Thanks a lot in advance.

Maybe AD 8672 is good for your cause.
Quick comparison of typical values:
OP2177

• Voltage noise : 8nV/SQRT(Hz)
• Offset voltage(max.): 60uV
• Input bias current : 2nA
• Dual supply op : ±2.5 V to ±15 V

AD 8672

• Voltage noise : 2.8nV/SQRT(Hz)
• Offset voltage(max.): 75uV
• Input bias current : 12nA
• Dual supply op :±5 V to ±15 V

hiii rahdirs...

thanks a lot for ur reply...but i am looking for a single supply op amp...with the negative terminal grounded.
AD 8672 is again Dual Supply..

I am not exactly sure but take a look at this thread,https://www.edaboard.com/threads/289723/.
From the above thread,i'm not exactly sure but i think you can use AD 8672 as a single supply(with V+ pin at 12 V & V- pin at GND)also as long as the potential difference between the V+ & V- pins does not exceed 36 V.
