Hi Sandeep, 

Please refer to our previous post, where you ask the same question.

https://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/1118287/xtr117-xtr117

 The XTR300 and XTR305 can be configured as 3-wire current transmitters.

The XTR300 and XTR305 can either source or sink current, or provide a positive/negative output as documented both on the XTR300 and XTR305 datasheet or TIPD155.

 The standard circuit for current output mode on figure 3 of the datasheet shows the transfer function for the XTR300 and XTR305, where the current output is a function of the input voltage.

Thank you and Regards,

Luis
