Other Parts Discussed in Thread: OPA569
Hi Team,
My customer plan to use a buffer to drive high current from a amplify.
Below is the basic requirement:
1.The output current better to range from 0~300mA. And 0~250mA is acceptable.
2. The resister load is about 3.5ohm to 5ohm.
3. The working temperature is the room temperature.
Please help to reply below questions:
1. Can the BUF634 meet the requirement as above. If not, do you have the recommendation?
2. The datasheet indicate the BUF634 can output 250mA current. So is the current fixed, or it's a maximum current? The current will be changed according to the voltage swing and the resister load?
3. Customer use the SOIC package, if the output current is 250mA, do they need to add the Heat Sink in the surface of the unit? Any PCB layout need to be considerate?
3. For the maximum 300mA current, any other part do you recommend?
Please look into the questions as above!
Lacey
Thanks a lot!
