XTR305: Maximum current output

Vitor Silva2

Part Number: XTR305
Other Parts Discussed in Thread: XTR111, OPA192, INA592

Dear TI Masters,

XT305 and some other ICs are able to deliver an output current from 0 to 24mA, but I'm in need of some 4mA more. It means an output current form 0 to 28mA.

Are we able to somehow make the XT305 work in this range? If not, do you have any other IC which could do the job?

Thanks!

Hi Vitor Silva,

Unfortunately, XTR306 can deliver up to 24mA, as you can see in its datasheet.

How about XTR111?
It can support up to 36mA with the external MOSFET.

Or you can consider the Howland current pump circuit with opamps, referring to the below application note.

If you ere interested in this circuit, I would recommend INA592 and OPA192.

Thank you and Best regards,
