Part Number: PGA280 Tool/software: Hello,
I am seeking guidance regarding the PGA280. Specifically what the input min max voltage range is for the SPI signals. The datasheet is somewhat ambiguous. It states that Signal input terminals, voltage cannot…
Hey Benjamin,
No update on an IBIS model yet. It will likely not be ready until the following year as I continue to ramp up on these devices.
I will post an update on this thread when I have one.
All the best, Carolina
Part Number: PGA280 Tool/software: Hi folks! I would like to use this part for it's GPIO/SPI CS expansion only and not use any of the inst amp side of the chip. It's easier and faster than implementing a small micro... Can you confirm if this implementation…
Part Number: PGA280 Other Parts Discussed in Thread: PGA281 , MUX36D08 Hello TI,
We're using the current sources on the PGA280 with great success to measure an estimate of loop resistance. It's working very well for loops of less than ~20K Ohm.…
Hi Kenneth,
Unfortunately there is no IBIS model or equivalent for the PGA280 SPI interface. If you require more information about the PGA280 SPI protocol or characteristics, please refer to the links below.
The digital I/O characteristics are specified…
Part Number: PGA280 Hi Teams,
I noticed that with VCP-VSN, the max Iq is 3mA( see pic ). Whether there will be some operating condition in which PGA280 pulls a current > 3mA?

Part Number: PGA280 Hello TI,
The PGA280 datasheet recommends R/C filters on each of the supply pins, however the example in the datasheet and the EVM both have VSON directly connected to ground with no series resistance.
For best performance, when using…
Part Number: PGA280 Other Parts Discussed in Thread: PGA281 ,
Good day,
In a lot of the reference designs that utilize the PGA280/281 (Including the SBOM817 TINA File for PGA281), I see some light load resistors added to the PGA Output (2.5K in the case…
Part Number: PGA280 Other Parts Discussed in Thread: OPA192 Hello TI,
Is there any data or specifications for the off-state leakage current of the input switches (A1/A2 & B1/B2)?
I would like to connect them to very high impedance inputs in order…
