Part Number: TIDA-00788 Other Parts Discussed in Thread: PGA300 , USB2ANY Hello
We want to use the TIDA-00788 4-20 mA Transmitter layout based on the PGA300. Which OWI to USB adaptor do you recommend beside the EVM board? Can we use any USB to OWI adaptors…

Hi Naveen,
Sure, check out this TI Reference Design: https://www.ti.com/tool/TIDA-00788 - Industrial Current-Output Pressure Sensor Transmitter, IEC61000-4 Tested Reference Design
I'd recommend you check out the PGA305 too. It has a bit higher resolution…
Hello Gibson,
Can you monitor the pressure inputs on your PCB with an oscilloscope? It would be good to confirm if this is noise on the inputs or if there is something going wrong internally due to a potential incorrect connection.
I also recommend reviewing…
Hi Vinay,
Scott provided you with details and a reference schematic in this post: https://e2e.ti.com/support/sensors/f/1023/p/925699/3420157 Click the link in that post for the TIDA-00788 reference design and scroll down the page for the example PGA305…
Hello,
You are welcome to share your schematic if you have any concerns. The PGA300 normal operation current is in the 2-3mA range, so as long as any external components do not draw enough to push the total over 4mA, the PGA300 will be able to regulate…
Part Number: PGA300 Other Parts Discussed in Thread: TIDA-00788 , I have bought PGA300EVM, which can be configured by computer. And according to TIDA-00788 made pcb, I want to connect TIDA-00788 PCB to EVM for configuration, while unplugging the PGA300…
Hello,
Yes, the PGA300 can be used for 4-20mA current output. This is listed on the first page of the datasheet here: www.ti.com/.../pga300
Hardware connections, including a full output schematic are described in detail in the applications section of…
Hello Vinay,
The PGA305 datasheet includes an application section which has an example of how to configure your external circuitry for a 4-20mA current loop application. The section is titled "4-mA to 20-mA Output With Internal Sense Resistor"…
Hi Ibrahim,
Not all of that is strictly necessary for the PGA300 to work, however the components highlighted are important for EMI immunity and in order to pass IEEE testing. For reference, please see this current output reference design which was tested…
