Hi Alone,
Alone173 said: But now we need a low-cost solution.
Could you please help to check and give me an advice for Opamp and Vref ?
Please provide me with the additional information.
Are you good with the existing LMP91200 pH sensing performance?

Hi Raymond,
as you show in OPA391 V2I Step Response 06162023.TSC this what we want to use and now back to my 1st question, is there an OP available with integrated NPN? (becaues I need to save space on the PCB)
Hi Vihang, First, I would recommend taking a look at this document . It goes over a relatively easy process of designing your circuit using a single amplifier.
By following the equations and assuming a VREF of 1.8 V, I made the circuit below.
As you can…

can you provide a solution for customer request I have received. The customer want to measure the TMR resistor chain and the RTD with the…
I recommended a similar to TLV333, low supply voltage OPA391 while OPA191 is a high supply voltage up to 36V. Nevertheless, they both have standard pinout and should work on 5V supply voltage you use in your application.

I designed sEMG PCBA with INA333 as first stage of amplifier,first time I used the same SCH as bellow,and the ouput signal is correct.
The secon…
Hi Stefan,
Stefan Langer said: For TLV900x there are no over-temperature-range/max-ratings for input offset and bias currents given, and typical values of 2pA can be considered as "not so good" compared with other opamps.
I didn't want to recommed…
