Part Number: OPA191 Hi,
Could you please tell me the internal circuit design techniques in detail to improve EMI immunity if possible ?
Best regards, Kato
Part Number: DAC8564 Other Parts Discussed in Thread: OPA333 , OPA317 , OPA391 , OPA191 , XTR111 , XTR300 HI SIR
I want to design a 4-20mA Function which use the DAC8564,
Did you have suggestion AMP for this?
thanks
In order to minimize the input offset voltage, OPA188 is a chopper stabilized amplifier as such is not the best op amp to implement a full-wave rectifier of AC signal. OPA191, OPA192, OPA196 or OPA197 would be a better choice. Having said that, in order…
Part Number: OPA191 Other Parts Discussed in Thread: TINA-TI Hi,
I am just about to use the OPA191IDBVT op-amp as a non-inverting amplifier, with the op-amp being powered from +5V and 0V.
My question is if the + input on the non-inverting amplifier drops…
Part Number: OPA191 I have built and tested a LC Oscillator around the OPA191-Q1 part.
The OPA191 is connected to a single rail 20V supply.
The OPA191 is used as a comparitor, the +Ve In terminal is connected to Gnd and the -Ve In terminal is connected…
Part Number: OPA191 Other Parts Discussed in Thread: REF5025 , REF6025 Hi,
I would like to reduce the reference noise of the underneath schematic. I tried to use the REF5025 (image under schematic) but according to TINA this only increases my output noise…
Part Number: OPA191 Other Parts Discussed in Thread: TINA-TI Tool/software: TINA-TI or Spice Models Hi,
In my last post I asked about the resistor values in case my opamp input was between 0 - 4.096V and output ±10V I did the calculations and this was…
Part Number: OPA191 Other Parts Discussed in Thread: TINA-TI , Tool/software: TINA-TI or Spice Models I have difficulty with simulating OPA191 in Multisim. I copied the PSPICE model from TI website directly in Multisim.
Will appreciate any help.
Part Number: OPA191 Other Parts Discussed in Thread: MPY634 , MPY100 Hi Team,
My customer don't want to use ADC resources for the RMS calculation, I'm wondering do we have hardware reference circuit for the RMS caculation? thanks.
Hi Mareks,
Thanks for your quick response and suggestion on the precision amplifier. I have the following further queries:
Can OPA191 use straight away as a unity gain buffer for a 10uV low-level signal? Do we need to add any offset removal circuit in…
