XTR106PA Pin Information
The Texas Instruments XTR106PA is an integrated 4-20mA current loop transmitter that comes in a 14-pin PDIP (Plastic Dual In-line Package). Here's a brief overview of the pin configuration and functions for this device:

Pin Configuration:
VREG: This is the voltage regulator output. It typically provides a stable reference voltage used by other parts of the circuit.
RG: Provides connection to an external resistor which sets the transducer gain.
+EXC: Excitation Voltage Output Positive Terminal, often used to power bridge-type sensors like strain gauges or pressure sensors.
–EXC: Excitation Voltage Output Negative Terminal.
+IN: Non-inverting Input to the Instrumentation Amplifier; connect sensor signal here.
–IN: Inverting Input to the Instrumentation Amplifier; connect sensor signal here for differential measurements or ground for single-ended measurements.
REF OUT/TEST1: Reference Voltage Output / Test Pin 1 – Normally connected through a decoupling capacitor to ground, it can also be used during factory testing.
Pin 8 - 11: These pins are not generally assigned specific functions in typical data sheets and may be related to internal connections or test features depending on TI's design.
Iout/Vout (Output): Current Output/Voltage Output – The loop current output that sources into an external load resistance at V+, providing your standard 4-20mA signal based on input from +IN and –IN pins.
Pin 13 - 14: Like pins 8-11, these are typically not user-accessible pins and serve either no connection (NC), internal circuitry purposes, or factory testing configurations.
