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…
Hi Yimin,
1. Yes that is correct.
2. Can you please clarify your question? The application diagram you have posted shows an example design for a 4-20mA output mode circuit. The PGA900EVM User's Guide ( www.ti.com/.../sldu011a.pdf) also includes…
Hi Kenji,
The current output mode is selected by changing the OP_STAGE_CTRL register to enable it:
You will have to set bits 0-2 to 0, and bit 3 to 1 for current mode. This must be set in the EEPROM, or the device will return to voltage output…
