Hi Team,

Can you please help with INA826 below parameters for +5V operation, datasheet specified for +/-15V operation.

input offset current?

input bias current?

input stage voltage noise?

output stage voltage noise at gain = 4.

Please help with inputs.

Regards, Shinu Mathew.

Hi Shinu,

if these specifications would exist, you would find them in the datasheet, I guess. Nevertheless, the performance will not differ all too much, as you can see from figure 29, 30 and 36. This is related to the fact that many of the operatings points in a modern OPAmp are controlled by constant current sources, which heavily minimizes the influence of supply voltage changes on the performance of OPAmp.

Hello Shinu,

I can help you. The only data we have for the INA826 is for +/-15V as shown in the datasheet. Kai is correct, these specs don't vary much with supply.

However, we do have a portfolio of 5V INAs in case you want to browse, you can find them here: http://www.ti.com/amplifier-circuit/instrumentation/products.html#p358max=5.5;10

Hi Tamara,

Thanks for the inputs.

Can you please suggest spec equivalent P2P for AD8226ARMZ-R7. I am getting INA826 as the closest match.

Regards, Shinu Mathew.

Hi Shinu,

You're right, the closest cross we have to the AD8226 is the INA826. Have you tested this device? You can order samples here: http://www.ti.com/product/INA826/samplebuy
