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: 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 of…
Hi Bini,
Do you mind sending over your Pspice project? I can take a look myself to see if there is anything we can do.
Surely some of this is coming from power losses in the rectifier diodes. Some can also be from losses in the Riso resistors.
What…
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).…
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. …
Part Number: OPA549 Hi Team,
My customer has some questions. Could you kindly answer the below quesitons?
① What's the meaning of disable/enable time in the datasheet?
After Enable get high, It takes 1us for OPA549 to output the signal?
② Is there…
Other Parts Discussed in Thread: OPA549 It seems that the contents described in the operational amplifier OPA549 data sheet and the actual operation of the product are not consistent, so please check.
In the POWER SUPPLIES section of the OPA549 data sheet…
Part Number: OPA549 Hello,
I am building a battery charger and discharger, and I am using a OPA549 chip to supply current to the battery to charge and discharge the battery. Below is the schematic I am using currently.
I have a reference voltage of 12…
Part Number: OPA549-HIREL Hello, My question is regarding the OPA549MKVC, which is the hi-rel straight lead package for this op-amp. They are flat leads with considerable width and thickness, so for a footprint with all thru-holes in a straight line the…
