Part Number: ADS127L11 We are trying to read the ADC value from PSoC 5 (Cypress microcontroller). But we are unable to read the right values. Count is changing , when we change the input voltage. But did not get any pattern. Difficult to understand that…
Hello Realathu,
Yes, I can provide some updates once this is resolved. Please note that the device can be damaged if the AVDD supply is accidentally shorted to the CAPA pin (these pins are directly next to each other on the ADC).
Also, we have example…
Part Number: ADS127L11 Other Parts Discussed in Thread: LM358 , OPA320 , LM7705 Not Getting resolution in microvolts. When we apply a voltage signal(up to 10 millivolts) to ADC, not getting the required counts. But when we apply a signal greater than 25…
Part Number: ADS127L11 Hello,
Based on below table from datasheet.
if analog input = 4.096V,
- the typical INL error = 0.9ppm *4.096V = 3.686uV
- the typcal offset error = 30uV
- the typcal gain error = 200ppm * 4.096 = 819.2uV
so, total error = INL error…
Part Number: ADS127L11 Hello,
Should use 4 oscillator or 1 oscillator + clock buffer?
I suppose 4 oscillator will be better for layout and EMC.
Both solution can be synchronized by start signal.
Let me know your recommendation.
Part Number: ADS127L11 Hi team,
customer test the latency of ADS127L11 and found the result is different from the data in datasheet. Customer used synchronized mode and use 25MHz as Fclk, 400ksps as data rate, OSR=32, Sinc4. According to datasheet, the…
HI Adam,
I just got back to office. Yes, from the THP210 perspective, using a 25kΩ and 50kΩ nominal resistors at the VOCM pin places the output common-mode at 3.3278V when accounting for the impedance loading of the internal 5MΩ+5MΩ voltage divider on…
