Hi Jagrutkumar,
As the OPA544 is a linear amplifier, when it is configured as a buffer (as shown in application note) it will attempt to maintain an output voltage that is equal to the voltage at the non-inverting pin. The output stage will source or…
Part Number: OPA544 Hello,
We apply the two package of OPA544 as a emmitter follower.
Under no load condition, the power consumption of OPA544T is about 100mA , and OPA544F is only about 25mA.
we would like to ask if the power consumption of OPA544T is…
Thank you for the detailed answer.

If I summarize it in a table, it looks like this, but why does the TI website show OPA544 as specified temp…
Part Number: OPA544 Other Parts Discussed in Thread: OPA548 HI Sir
I use opa544 as a voltage source to test the DUT. There will be current measurement circuit between the lines. Sometimes the current circuit will oscillate, But when replaced with OPA548…
Part Number: OPA544 Dear team,
I am using OPA544 OP-amp to build gain amplifier. To power-up Op-amp i have positive 60V DC power source.My question is ,
1. To power-up OPA544 should i need both positive and Negative voltage ? or will it work only with…
Part Number: OPA544 Hi Raymond,
We have performed tests with the circuit recommended by you (attached with the component value changes) with the change of the L&C values.
L & C Values recommended: 10mH & 1uF
L & C Values used in the circuit…
Part Number: OPA544 Other Parts Discussed in Thread: OPA549 , OPA548 , Good afternoon,
I have been looking at the document entitled, "Building Your Own Battery Simulator" (Application Report SLVA618–October 2013) I would like to make use…

Part Number: OPA544 Is there any problem or issue if we didn’t give power for +V but we maintain –V for OPA544T and will not give any input signal also during this time? we don’t expect to OPA544T as working during this time But would like to know whether…
Part Number: OPA544 Other Parts Discussed in Thread: TINA-TI , Our design uses OPA544T.
Test results of the circuit with the OPA544T does not match with the simulation results.
Datasheet of the OPA544T includes the following information:
It looks like …
