Part Number: TIDA-01536 Other Parts Discussed in Thread: XTR111 We are having some issues with XTR111 susceptibility to external noise. For example, when we perform the IEC61000-4-6: Conducted Immunity test, we are measuring up to 8Vpp noise on a 10V…
HI Stephane,
That's great news, glad the device is working.
Please check below the TIDA-01536 Design Guide, the reference design features a precision DAC and XTR111, with a digital isolator.
The design includes TVS diodes, and a couple of resistors…
Part Number: XTR111-2EVM Other Parts Discussed in Thread: XTR111 , TIDA-01536 Hello everyone, I'm using the XTR111 to convert a 0-5V input voltage to a 4-20mA output, as shown in the picture below.
I would like to know in this case the transfer function…
Hello Shirbin,
Regarding the overall XTR111 circuit accuracy, the errors will be a heavy function of the DAC or the circuit generating the input voltage signal of the XTR111, the reference of the DAC; as well as the XTR111 gain error, offset, linearity;…
HI Chirag,
Below is a link with a list of the existing current transmitter reference designs; there a few designs that may be of interest, or provide circuit blocks / design ideas.
[FAQ] Are there reference designs that can help me build a 4-20mA…
Part Number: XTR111 Other Parts Discussed in Thread: XTR117 , TIDA-01536
Hi Support Team,
I have browsed few threads on 4-20mA loop transmitter on e2e forum from this post and this post , my understanding a 3-wire transmitter (XTR111) is used for…
Part Number: XTR117 Other Parts Discussed in Thread: XTR116 , , OPA2188 , XTR111 , TIDA-01536 Hello,
I'm building an isolated bipolar +-10V or current 4mA..20mA output module.
The voltage generator use an SPI isolator and 16 bit DAC.
The power lines…
Hi hechengwang ,
Honestly speaking, the appropriate value of the output cap for XTR111 is depending on the system requirements such as noise immunity, radiation noise, intrinsic safety, et cetera.
While, you can also refer it to the subsection "DYNAMIC…
Hello,
You can take a look at the TIDA-01536 XTR11 reference design. Section 2.3.6 provides recommended protection circuitry.
You can also take a look at this blog post that goes into some more detail on p rotecting 3-wire analog outputs . In…
Hi Prajwal,
1) The analog front-end consists of a shunt resistor followed by the TLV333 amplifier in the non-inverting configuration. The inverting path is referred to a reference voltage to shift the output to 0V when the input current is 4mA. The…
