Other Parts Discussed in Thread: INA241A , OPA320 , ADS8860 , REF6050 , ADS1220 , TINA-TI , INA296A Dear ladies and gentlemen,
I want to convert a PWM signal of 10sec. t_on and t_off (in total 20sec.), which is amplified to a range of approximately…
Marvin,
I ran a simulation and it looks like it does settle to 1/2 LSB according to the circuit you described. Attached are the simulation results summary in a PDF. I also show an alternative filer that will minimize the noise and potentially improve…

Tran,
1. The Ref pin on INA331 is used to shift the signal. This should be connected to Vref/2.
2. The positive supply on INA331 is connected to a voltage equal to Vref. In the example circuit I showed 5V. Note: I would use an LDO to generate the…
Part Number: ADS8860 Other Parts Discussed in Thread: REF6030 , REF6050 Hello Keith,
Now I am trying to use 2 ADC to obtain 2 channel input for 2 process values using ADS8860 EVM in prototype stage.
I have connected it in the following way to use…
Hello Anthony,
It appears that you have a timing issue in your communications. If you could capture the waveforms using a logic analyzer or an oscilloscope, that would be helpful.
If I am reading your code correctly, it appears you have /CONVST inverted…
Part Number: TIDA-01053 Other Parts Discussed in Thread: ADS9120 , REF6050 , OPA625 I want to design a high precision, high dynamic range ADC front end for ADS9120 using OPA625 and REF6050, and 01053 is right there. But there isn't any pdf files regarding…
Hi Eren,
The above circuit looks alright; however, do note that the accuracy of the LM4050 (A grade) will be on the order of 0.1% at room temp; so the reference source may contribute more error than the resistor divider and buffer circuit.
....Something…
Hi Imran,
what's your SCLK frequency? what's your CPOL and CPHA? It seems that one data bit is missed, every data bit should be read during 5ns after the falling edge of SCLK (t2 shown in the picture as below and also please check the timing table in…
Hi Dennis,
I know you are also discussing this topic with Chris around the ADS1261 on the other thread but I wanted to add my two cents here as well.
If your sensor or application doesn't mandate current excitation, then I would recommend to go with…
