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…

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 : 1V/V After Vin…
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…
Part Number: PGA855EVM
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…
Hi David,
Below is a quick measurement with the PGA855EVM. The device is powered up with Vs+/Vs- = ±5V (input supplies); LVDD+/LVSS- = ±5V (output stage supplies, VOCM driven to +0.9V. Removed the PGA855EVM filter input capacitors (C6, C13…
Hi Martin,
Performed measurements with a couple of PGA855EVMs. On this setup, I used a 2-channel waveform generator (Agilent 33500B) to generate the 3MHz and 3.3MHz fully-differential signal. The PGA855EVM was left un-modified with the input and output…
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…
