DAC81404: How to get a information for 'High Current Drive (1 A) Application' in DAC81404/DAC61404 datasheet?

Hi Lee SungYun,

Akhilesh will help with this when he is back in office after the local holidays.

Thanks,

Paul

Thank you for reply.

I'll waiting for that person to come back.

Is that person coming next year?

Yes, the will respond on January 2nd.

Hello?

I've reviewed DAC81404EVM, but it is slightly different from the application on the datasheet.

In datasheet, it is completed with a pair of transistor and a combination of resistor + capacitor.
On the other hand, the circuit you told me requires a fairly large area as 4 resistors and 2 diodes are added to 3 transistors.

Accordingly, we ask for the resistance value and the product name of the transistor used in the 1 A application on the datasheet.(Ccomp is assumed to be 470 pF)

In addition, in the case of the EVM circuit, if the load is increased to 200 mA, I would like to ask if there is any element limiting the current or if only the resistance of 5 Ω and the heat dissipation of the transistor can be considered.

Thank you.

I'll review 2 applications.

Thank you for reply.
