My ctm evaluate PGA302 now,some questions as below,

1. How to achieve 4~20mA current output and TI can provide sch. or not?

2. PGA302 supports ratiometric voltage output , how to achieve fixed voltage?

3. How PGA300 & PGA302 can unify to the same platform with the calibrated software & tools?

Many thanks.

Hello,

1. The PGA302 does not have a current output mode. The only available output mode is the ratiometric voltage output.
2. The only option for the output is a ratiometric voltage output.
3. The PGA300 and the PGA302 are not pin compatible. Communication with the devices can be similar with the OWI protocol, however the register maps are different, and they cannot share an identical setup.

Regards,
