Part Number: OPA4325 Other Parts Discussed in Thread: OPAMPEVM-MSOPTSSOP Tool/software: Hello, My customer would like to evaluate OPA4325(14pin TSSOP). Does TI have any DIY type universal EVM for this? (I can see OPAMPEVM-MSOPTSSOP, on TI web, but it…
Hey Roger,
This app note covers how we modernly test our op amps: EMI Rejection Ratio of Operational Amplifiers (With OPA333 and OPA333-Q1 as an Example)
Figure 10 shows the circuit configuration, the DIY amp boards can be used to build a buffer (gain…
Hi Shawn,
The closest PCB evaluation board I found as far to implement the current inverter circuit, is the Dual-channel universal do-it-yourself (DIY) amplifier circuit evaluation module:
DUAL-DIYAMP-EVM
Dual-channel universal do-it-yourself (DIY) amplifier…
Hi Zach:
My voltage generator is just several 9VDC transistor batteries connected in series. Like you suggested, I will limit my working voltage to < 50VDC. That is, I will charge my home-made capacitors to < 50VDC. Then, I will use a voltage divider…
Hi CELESTE GONZALE ,
It is not easy to check your timing. Below is a timing example captured on ADS131M04 for reading CFG register(0x06 address) which was already written 0x0700 to enable Global-chop mode with a default delay in the previous step. As you can…
Hi Gertjan,
Gertjan Maenhout said: We have a LP876411B4RQKRQ1 on a custom PCB. To operate it properly, we would like to change the NVM through I2C as asked before ( link ).
As mentioned in the thread that posted a while ago. We are working on to release…
Hi Joe,
Thanks for checking this on your side.
After thorough review of the issue and the EVM in general, I've identified the root cause and some workarounds:
There is a PCB error in the EVM, which has to be addressed in a new revision on the next…
Hello Joey,
Unfortunately, this device doesn't have an EVM. We do have a DIY Adapter EVM that includes the device's package (SOIC-8 [D] and SOT23-5 [DBV]).

Josh
John,
Thank you for the feedback. And apologies for not defining the issue at hand.
A little background on my issue at hand. I have managed to make a DIY Capacitor (12inchesx12inches) using two copper sheets and polyimide film in-between serving as a…
Ok, So you mean no need to calibrate EVM board for Voltage / Current / Temperature ? Right...?
In case Calibration is required , Can you suggest few cost-effective power supply models can be used OR any DIY option for it ?
