Hi team,
A customer is interested in this reference design, TIDA-01513. And there's a part of it using OPA320-Q1. They were wondering, can they replace OPA320-Q1 with LM2904LV-Q1?
I notice there's a big difference in speed and offset, but is there any other major difference between then? Making it hard to use LM2904LV-Q1?
Thanks in advance
Kind regards,
Sam
I was also wondering, does it exist any TINA-TI simulation data for this? Which is accessible for customers, we're in the process to obtain an NDA with them.
Kind regards,
Sam
Hi again,
They are now stuck with gain calculations for their requirement. They have a TinaTI circuit which they attached in the e-mail, can I send it through e-mail to you?
They wrote like this:
"
Can you please help us with explanation on how input and feedback resistors are selected?
Our requirement: HV input range= 0 to 84V, Vref= 1.65V, Vsupply to opamp= 0 to 3.3V, Viso out= 0 to 3.3V ADC range.
I am trying to use Inverting op amp with non-inverting positive reference voltage circuit (Rev. A) formulas but it does not work as expected and not sure what I am missing.

Kind regards,
Sam
