FAQs

What is XTR115U?

The XTR115U is a precision, low-drift 4-20mA two-wire transmitter designed by Texas Instruments. It is commonly used in industrial automation and process control applications to convert voltage signals to 4-20mA current signals for transmission over long distances.

How Does XTR115U Work?

The XTR115U works by accepting a low-level voltage input and converting it to a 4-20mA current output. It incorporates a precision low-drift internal reference and an internal amplifier to provide accurate and stable current output. The device is designed to operate with a supply voltage as low as 7.5V, making it suitable for loop-powered applications.

How Many Pins does XTR115U have and What are the Functions of the Pinout Configuration?

The XTR115U is housed in a 16-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:

  • V+: Positive power supply pin.
  • V-: Negative power supply and output common pin.
  • IN+: Non-inverting voltage input pin.
  • IN-: Inverting voltage input pin.
  • REF: Reference output pin for external use.
  • OUT: Current loop output pin.
