Part Number: DRA821U Other Parts Discussed in Thread: DRA821 Tool/software: Dear Sir,
Is there DRA821 power consumption measurement data for DRA821 EVM?
There are INA on EVM for each power rails.
Is there a script which customer can use to read out all…
I have a similar question. The Jacinto7 DRA821 Evaluation Module (EVM) is capable of measuring the load current via the INA Device mounted on the circuit, but we are currently unable to get it to work properly. Could you please provide us with any data…
Hi Holly
Let me clarify the items. 1. Yes, what I mean of Vcc&Vs is supply power on Pin3. the following is the schematic, RS1&RS2 are current sense resistor ， +12V is the output voltage, 12VSB is standby power for INA. Customer used this device as…
Hi Amanda,
The Processor SDK doesn't provide a tool to read the INAs on the SK evm from Linux command line. But you might try to port the following program and use it to read the INAs.

Hi Dietrich,
Dietrich Rushing said: Also i mentioned over current protection long ago and how to add it in this circuit, i will research available options and the decide current sense method then return here.
Shunt + INA amp or hall effect IC what do…
Hello, Apologies for the delay as I was in training last week. I2C addresses of the INAs have changed from revision to revision of the EVM. Can you modify the code to support these I2C address of the Supply Net? Best Regards. Anshu
Part Number: DS90C187 Other Parts Discussed in Thread: AM5729 , Tool/software: Hi Experts,
Good day!
I am posting this on behalf of the customer.
Here are the full details of the inquiry:
I want to use this device in the Single Pixel In / Dual Pixel Out…
Other Parts Discussed in Thread: AFE4300 Hey,
I was going through the schematic for the evaluation module and noticed that a DC bias (~1.7V) is added to the signals when using the INA (U5). I am assuming that this was done so as to bring the signal upto…
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…
