Part Number: XTR300
Hello there, Hope you are doing well. In one of my system i want to use two XTR300 (one for voltage output and one for current output). Those both XTR300 will be operated from the same power supply . I have different choice from below options. But to make it lower cost (assume that less current will be lower cost for me) 1) +-12v (+-33mA) 2) +-12v(+-43mA) 3) +-12v(+-75mA) 4) +-12v(+-83mA) 5) +-12v(+-100mA) 1) +-15v(+-25mA) 2) +-15v(+-33mA) 3) +-15v(+-43mA) 4) +-15v(+-83mA). in the datasheet supply input current shows +-25mA. But still i want to confirm that is it maximum current xtr300 needs to operate on full scale ?Thanks,Bhautik
Thank you for your post. I assume you are referring to "ABSOLUTE MAXIMUM RATINGS" table on page 2 of the datasheet where it says the Signal Input Terminals maximum current is +-25mA. This is the maximum current into the input of the XTR300 that is allowed before device damage may occur. If you sustain +-25mA or more on the inputs of the XTR300, this may cause permanent damage.
Please let me know if this is what you were referring to in your post.

Hello Tamara, Thanks for your detailed reply. Your reply cleared many things. I just have now concern about the "V+"(pin 15) and "V-"(pin 11) pin of the XTR300. Are they also limited to the +-25mA. If not then howmuch maximum and howmuch minimum current requires there. As i want to select low lost power source (power supply source) for it.Thanks,Bhautik
In reply to Bhautik Ramoliya98:
The supply current for the XTR300 is shown in the datasheet: page 7 ELECTRICAL CHARACTERISTICS under the section titled "POWER SUPPLY".
The quiescent/supply current is 1.8mA typical and 2.3mA maximum.
However, it is recommended that these supplies never exceed 44V, as shown in the ABSOLUTE MAXIMUM RATING table.
