Hi.
I recently received a defective part related to my purchase.
Description of the situation 1. VS+ :+12V Vs- : -5V LVDD : + 5V LVSS : -5V(VS랑 SMPS) Gain…
Part Number: PGA855EVM Other Parts Discussed in Thread: PGA855 Tool/software: I just purchased the PGA8555EVM board. It looks like my version is E1. Manual shows errata notes for E2 but nothing for E1. Not sure why I got shipped (from Mouser) a EVM that…

Hi TI,
I found that when I change the gain setting on the EVM, the bias current also changes.
The PGA855 is powered from +30V and -4V, with VCC = LVDD+, VEE = LVSS…
Part Number: PGA855EVM Other Parts Discussed in Thread: PGA855 Tool/software: Hi TI,
I am trying to characterize the device behavior when the VICM range is exceeded or inputs are overloaded/saturated, specifically, what would happen to the current consumption…

Hello Team,
I'm looking for the design files of the PGA855EVM, is this available? The user guide contains the Schematic, PCB Layout, and Bill of Materials is there a possibility to have the design files of the EVM?
Regards…
Part Number: TPS65131 Other Parts Discussed in Thread: PGA855 , INA823 , PGA855EVM Tool/software: Hi Patrick,
I apologize for reviving the old post now ( TPS65131: Noise issue on dual DC/DC converter ). I measured the current across resistors R118 for…
Hello Guillaume,
Since there were several issues with the SPICE model convergence of the PGA855, it has been pulled from the web, and evaluation is encouraged with the evaluation module. Is there some specific behavior you had a question about?

Hi Jenny,
Lets start with the products themselves.
PGA855 is a good cross with the ADI LTC6373 device.
Both devices are fully differential PGAs with similar gain ranges (TI has 1/8 min gain whereas ADI has 1/4 gain minimum). Both are HV 36V devices…
Hi Carolina,
No problem. I completely understand.
Is it possible there's a bug in the calculator? It doesn't reflect my measurements of PGA855EVM the at all.
Here are my settings in the calculator:
Here is a measurement I took with my oscilloscope…
Hi Hao,
On the PGA855 bench setup, the input and output filters of the PGA855EVM were removed, and the inputs of the PGA855EVM were shorted by replacing the differential input capacitor with a 0Ω resistor; in other words, placing a short right at the…
