Other Parts Discussed in Thread: TIDA-010037 , ADS131M04 Hi,
Good Day.
The customer is testing the TIDA-010037 board and he runs the SW application to get measurements of energy parameters, like the voltage, current, and active power.
The update rate is…
Part Number: TIDA-010243 Other Parts Discussed in Thread: ADS131M08 , , TIDA-010037 , TIDA-010036 Hi team,
I have some questions about this reference design:
In TIDA-010243, our ADS131M08 OSR is set to 512 with a sampling rate of 8KHz, can I set OSR=256…
Part Number: TIDA-010037 Hi
In this reference design why such small input voltage is selected for the voltage sense. If the ADC has full scale of +/- 1.2V , why not use at least half of the full scale range?
In our application, the energy meter is near…
Hi CSC,
Thank you for your patience, I was able to find the site where we acquired the CTs for the TIDA-010036 and TIDA-010037. TIDA-010037 is a Split-phase metrology reference design for electricity meters that meets ANSI C12.20 Class 0.1 active energy…
Hi Christos,
And you're talking about the bias current from the ADC correct? Let me check internally and get back to you in the next couple of days.
In the mean time, I would recommend you take a look at this reference design: https://www.ti.com/tool…
Hello Arion,
ADS1178 has the following DC specs:
These specs do not include any errors due to external amplifiers or reference. With calibration, you can design systems around this device with total error over temperature of 0.1% or better.
If you are…
Hi Arion,
ADS130E08 does not have a special requirement for the controller, it needs a SPI interface:
Maximum SCLK frequency: 20MHz for 3.3V DVDD.
Minimum SCLK frequency: you need to clock out all the data before next conversion, so the minimum SCLK…
Hi Imelda,
Imelda Zhang said: 1. I use the excel of CS calculation sheet to calculate some parameter. Resolution(mA)=0.1/B3*1000. It seems that the resolution just has relationship with shunt resistor. From my perspective, the resolution do has some relationship…
Hello Pedro,
Between the TI reference designs, "Active Integrator for Rogowski Coil Reference Design with Improved Accuracy for Relay and Breaker" and "High accuracy split-phase CT electricity meter reference design using standalone ADCs" should be able…
Hi Danilo,
Sorry for the delay:
Danilo A. said: Our customer would like to know when to isolate the SPI bus of ADS130E08 from the microcontroller?
I'm not super knowledgeable about this but it relies heavily on what the system or applicable is. In 3 phase…
