Hi Felipe,
It may be able to use OPA205 or OPA2205 or OPA4205 or even the initial OPA4209 part. The issues are your input voltage is too small and you do not have gains in the test circuit. If you have gain of 200 initially per your test configuration…
Part Number: OPA2340 Other Parts Discussed in Thread: OPA4205 , DAC8822 The OPA4234U is TI part which is obselete now. Kindly send the LTSPICE model for this part for design analysis
