Part Number: OPA549 Other Parts Discussed in Thread: OPA569 Tool/software: Hi,
I'm going to use the OPA549 to drive a servo dc motor. However, one of my motor terminals is not ground, so I think that using two OPA549s as differential amplifiers. Is…
Part Number: OPA549 Other Parts Discussed in Thread: OPA541 Tool/software: Hi,
I need use OPA549 as a single supply. What kind of circuit diagram should I use? What should my input signal be?
Regards
Part Number: OPA549 Tool/software: Hi,
Plesae check our OPA549 schematic diagram, why our OPA549_ISET is only about 4.3A and the VIN_OPA is more than 7A, thanks.
Part Number: OPA549 Tool/software: Used in a circuit with ±24 V supply and 8 A DC current into 1.25 Ω. It is not known why the thermal shutdown is activated at about 4 A DC. The fin temperature of the package only rises to about 60°C. Can the thermal…
Part Number: OPA549 Tool/software: Hi Sir / madam,
We have one design with LM12C in which we are replacing the LM12C amplifier with OPA549S.
LM12C is used as current drive, also having configuration of current drive as servo driver, So there are 2…
Part Number: OPA549 Tool/software: Hi!
In the OPA549 Simulation (attached the screenshot as well as the simulation file), I get an error stating, "Pin OUT of Subcircuit U1 is in conflict with Pin OUT2 of subcircuit U1" (same for U2 as well).
The datasheet…
Part Number: OPA547EVM Other Parts Discussed in Thread: OPA549 Tool/software: Hello, is there a similar EVM available for the OPA549? Even Gerber files would be enough to work with, no need for a finished EVM product.
Best Regards, Johannes Mathieu
Part Number: OPA549 Tool/software: I'm using three OPA549 connected parallelly, one master driving two slave. When 1VAC is applied as non-inverting configuration with gain of 10 getting clean output 10VAC without load. When 1ohm resistive load is applied…
Part Number: OPA549 Hi Team,
I am making a voltage controlled voltage source with OPA549, the following is the schematic diagram, I encountered two problems during use:
1) The power-on sequence of VIN+ and VIN- seems to have requirements: under…
