FAQs

What is XTR106U?

The XTR106U is a precision, 4-20mA current loop transmitter designed by Texas Instruments. It is commonly used in industrial control and process control applications to convert voltage signals to 4-20mA current signals for transmission over long distances.

How Does XTR106U Work?

The XTR106U operates by converting an input voltage signal into a corresponding 4-20mA current output signal through a precision current source. It provides linearization and calibration functions to ensure accurate current transmission proportional to the input signal voltage. The device is known for its high accuracy and stability in harsh industrial environments.

How Many Pins does XTR106U have and What are the Functions of the Pinout Configuration?

The XTR106U 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 pin.
  • VREF: Reference voltage output pin.
  • VSENSE: Voltage input pin for signal sensing.
  • VB- and VB+: Voltage input pins for offset correction.
  • IO-: Current output pin connected to the low side of the current loop.
  • IO+: Current output pin connected to the high side of the current loop.
  • IN-: Inverting input pin of the internal operational amplifier.
  • IN+: Non-inverting input pin of the internal operational amplifier.

What are the Pros and Cons of XTR106U?

Pros:

  • Precision: Provides accurate 4-20mA current loop conversion for reliable signal transmission.
