Part Number: XTR111-2EVM Other Parts Discussed in Thread: XTR111 , TIPD102 Hi,
I am designing a circuit for my application which is as described below
I/p: 0 to 10V
I/P step voltage: 10mV
O/P current: 0 to 1024uA
Compliance voltage: 12V
If I changed the…
Part Number: XTR111-2EVM Hello Sir,
Greetings!!
I have a question regarding the use of Schottky Diode D1 (SS16-E3/5AT) as shown in following figure.
I did not understand the use of Schottky diode in reverse bias with VSP rail while VSP is 24V.
Kind …
Hi Shibin,
Thank you for letting us known. An estimate of the XTR111 current consumption will be the quiescent current of the device(IQ), plus the ISET current and IOUT current consumption:
Current Consumption (approx) = IQ + ISET + IOUT = 550µA (max…
Hello Jimmy,
The XTR111 thermal pad connection is missing on the design. Please note, the XTR111 exposed thermal pad must be connected to GND to ensure correct/proper bias of the XTR111 internal circuitry. Please modify the design to ensure the XTR111…
HI Shiblin,
- The XTR111 is a current output transmitter. On the multiplexer circuit above, when selecting the RLOAD = 249Ω, the resulting output voltage will change with any additional load impedance or resistance applied at the output of MUX U38…
HI Daria,
I agree with Kai. If you would like us to review the schematic and PCB board layout please let us know.
You may also want to ensure the thermal pad of the XTR111 is connected to the GND, The leadframe die pad should be soldered to a thermal pad…
Part Number: XTR111-2EVM Does anyone know the dimensions of the XTR111-2EVM Evaluation Module visible at the link below? Thanks much.

Part Number: XTR111-2EVM Other Parts Discussed in Thread: XTR111 I have just bought a XTR111 EVM board. However, I have encountered several problems with the board. I have followed the procedures for the basic EVM configuration. But, I still cannot obtained…
HI Gonzalo,
The dominant portion of power dissipation for the current output is in the external FET. As Kai has explained, it is important to consider the power dissipated by the external FET, which is a function of the power supply voltage, and current…
Other Parts Discussed in Thread: XTR111-2EVM , XTR111 Hello,
I am trying to use the XTR111-2EVM as a current source to power the specimen. A sinusoidal wave oscillated at 100Hz~2000Hz will be the input signal. The peak-to-peak amplitude ranges from 0.5V…
