PTH08080W: PTH08080W with digital potentiometer

DTB

Part Number: PTH08080W

Hello,

Is it possible to use a digital potentiometer connected between pin 4 and GND to remotely set the output voltage ?

Is there any limitation?

Thank you,

regards

Sam

Hi Sam,

Yes, a digital pot can be used to set the output voltage.

I would recommend not changing the voltage any quicker that 0.5 V/ms.

Thanks, Jason

Thank you very much for your fast answer.

Do you know the maximum current/voltage that will flow thru the resistance?

The voltage on the ADJ pin will 0.9 V and the maximum current can be 0.5 mA.
