Paul,
One option is the INA EVM Landing page . The users guide is fairly detailed to explain how this can be used: INA EVM users guide
Another possibility for an evaluating any device is to use dip adaptor cards and hand wired discrete components: https:…
Hello Henrik,
Understood, this is not easy to work with. We do try to minimize the capacitance on the RG node. The RG node connects directly to the inputs of the INA's first stage amplifiers, which are sensitive to capacitance on some devices, therefore…
Hi Henrik,
Henrik Rosenø said: Are there any evaluation boards for the VSSOP-8 version? Henrik Rosenø said: I am not sure how to solder such microscopic pins?
I do not recall. SOIC-8 is the most common IA package, and it is commonly used in EVM purposes…
Part Number: J784S4XEVM
In the J784s4 EVM, there's INA devices on all the lines to the J7 SOC, except VDD_CPU_AVS and VDD_CORE_0V8. The INA devices to those lines are DNI in the schematic.
Is there still a way to measure the power consumption of…
Hi Rio,
The following documentation explains how to use and wake up low power mode on AM62x.

Hi Bright Robert,
Please use the UCC21550 instead. It contains many important bug fixes vs. the UCC21520.
1. You can use the LM5039 or UCC28086D to generate the input to the UCC21550, but make sure you attenuate the HO and LO voltages down to the 5V input…
Hi Craig,
Cool project! You are considering some important tradeoffs on the devices. Unfortunately I can't seem to find a plot showing the Vos vs Vcm data for the OPA1652 but I have experience with the device. The OPA1688 does have the Vos vs Vcm curve…
Hi Rob,
Pulse generator is an Agilent 33522A. The two outputs of the generator were directly connected to INA- (J3) and INA+ (J1) of the ADC-EVM.
We still use the test setup as already described but without the LMH3401EVM.
regards,
Andreas
Hi Andrea,
All the EVMs of Sitara K3 devices have the similar design which has INAs for measuring power consumption. The intention was to be able to measure power in any scenario, not only in A53 Linux, or not at Linux runtime. So there is no Linux tool…
Bhagyashree,
The schematic and routing are available in the User's guide:
https://www.ti.com/lit/ug/slyu055a/slyu055a.pdf
I have checked both for each connector on the PCB and they appear to match. Please note that there is no electrical connection…
