  • XTR116: xtr116 draws high current

    Part Number: XTR116 Other Parts Discussed in Thread: XTR111 When I first energize, the XTR116 draws 80 ma current. Since there is too much voltage drop over the 250 ohm resistor, the supply voltage (V + and IO) of the XTR116 drops below 7.5 volts…

  • XTR116: EOS Protection Issue

    TI Thinks Resolved
    Part Number: XTR116 Other Parts Discussed in Thread: XTR115 Hi Team, Some failures comes up with the phenomena that device can not generate the right current with different input and loop current stays at maximum. FA report shows the failure is caused…

  • XTR116: Selection criteria for and when to use the output capacitor

    Part Number: XTR116 Are there any app notes on the XTR116 that discuss the selection purpose, selection criteria and guidelines for the output capacitor. The datasheet doesn’t mention how to select this component, what effect the value has on the output…

  • DAC8740H: Using the DAC8740H with the XTR116

    TI Thinks Resolved
    Part Number: DAC8740H Other Parts Discussed in Thread: XTR115 , , XTR117 , XTR116 In your reference design for the DAC8740H family devices, I see you use separate a op amp, regulator, and voltage reference for the 4-20mA driver portion of the circuit. I…

  • XTR116: 4-20mA transmitter with 4 wire sensor

    TI Thinks Resolved
    Part Number: XTR116 Other Parts Discussed in Thread: XTR117 , XTR111 Hello, I am looking for a 4-20mA transmitter to connect to the output of my DAC. I have seen the XTR116 and XTR117 and was wondering if they would work with a 4 wire system? If not would…

  • XTR116: current limit issue

    TI Thinks Resolved
    Part Number: XTR116 Hi Sir, Pls reference below circuit, this circuit is work normally and the output voltage (VRL)= 5V (20mA*250ohm). If I swinging the Micro-USB cable, the voltage will increase to 7V and will latch till re-plugin this cable. I think…
