Part Number: OPA548EVM Hi, Good day. I hope you are well. Our customer wants to know the dimension of the mounting holes for OPA548EVM. The mounting hole dimensions, aka how far apart are they from each other for mounting. Also, the diameter. Thank you…
Part Number: OPA548EVM Other Parts Discussed in Thread: OPA548 I’ve setup the OPA548EVM with dual power supplies (+/- 12VDC) and input signals using the differential amplifier setup in the user manual , Figure 8, shown below. I have J2 (Vin-) as…
Hi Kai
actually my load could be much higher than 20 ohms and i need to pass a wide range of current to dissipate different power each time. the problem is the design is set for 20 ohm ideally. Iwas planning to put all that on a PCB to fit into my setup…
HI Kay, 1. what is ringing? you mean unsuitability? 2. When the opa548evm will be available, if not, are the same responses (with a smaller current) are similar in the opa547( i can work with 0.5 amps) One last thing can you please sent me a link to…
Hello Kai ,
thanks a lot for your help. I have prepared a "prototype board" using parts that i had already in my lab. As expected the IC was really hot but there was no heatsink at all . I am trying to find if there is something wrong or critical with…
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: OPA548 Other Parts Discussed in Thread: , LM7705 Hello. I'm having some problem comprehending the internal functions of op-amps and I'd appreciate any insight in to why my circuit behaves the following way: I'm working with the OPA548…
Hello Avinash,
For power electronics the thermal management issue can be as much work as the electronics portion of the project. Even if I were to recommend a different power op amp the same thermal management concerns would have to be addressed because…
