Hi Joel,
two final points:
To decrease the heat dissipation within the OPA544 you can choose a lower supply voltage for the OPA544. +/-25V should be ok.
Also, I think there is no need for U4 and U6 in your circuit. Or am I wrong? Can you tell me the reason…
Part Number: OPA544 Dear Sirs, good evening!
We got device OPA544T and it was written Burr Brown on the device Burr Brown. Could you confirm that this device is legal and is still manufactured by TI with the Burr-Brown logo? There is letter "B' on the…
Part Number: OPA544 Other Parts Discussed in Thread: OPA541 , OPA548 Dear Specialists,
My customer is considering OPA544 and has questions.
I would be grateful if you could advise.

I'd like to know the output stage of OPA544.
high current Opeamps…
Part Number: OPA544 I have a device that use the opa544 as audio amp. This device is manufactured for for several years with no problems.
Some devices of the last produced batch accidental have a too low output level.
The opa544 is used as non-inverting…
Part Number: OPA544 Other Parts Discussed in Thread: OPA548 , OPA548EVM I am using the DAC161S055 as a 0 to 5VDC source. I would like to increase the current drive to at least 3A with good 1:1 voltage following. It was suggested that the OPA544 or 548 would…
Part Number: OPA544 Hello Team,
I have a question about the reference circuit of "FIGURE 5". Is not it necessary to have a capacitor for phase compensation in the circuit?
Best regards, Kato
Other Parts Discussed in Thread: OPA544 , TINA-TI Hi TI members, My customer is designing V/I conversion circuit with OPA544. He found a difference result between that of TINA-TI simulation and actual evaluation, and wants to know a root cause. Could you send…
Part Number: OPA544 I need a constant current source(Sinusoidal) of Range (10-200 mA RMS ). The frequency range is also selectable from 1K to 6K with a frequency resolution of 1Hz. The current source shall be controllable with a resolution of atleast…
Other Parts Discussed in Thread: OPA544 I use OPA544 in voltage follower, and I refer OPA544 datasheet P8 . Figure 5 (output series L/R network helps assure stability with very high capacitance loads) in circuit, but when CL>0.1uF,voltage follower still…
Other Parts Discussed in Thread: OPA544 , OPA548 I need to minimize power dissipation in an applicaiton using the OPA544 at 1A into a 0.1 Ohm resistor. I would normally use ± 15V for the rails but this results in too much power dissipation for the heatsink…
