Hello, Caro Walter ! We are using Siemens HyperLynx to analyze signal integrity of switching signals and any coupling effects caused by switching signals. The main thing we care about in IBIS models are the drivers and receivers of switching signals (like…
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?
BRs,

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…

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…

Hello,
With regard to the VOCM pin, the datasheet always shows this connected to mid supply (VOP+VON)/2
Is there any harm to performance in setting VOCM off from center? I don't see anything…
Part Number: PGA280 Hi teams,
Can you help me about the questions?
Will error flag OUTerr be triggered only by overcurrent?(see the pic below)
If so, what’s threshold?
