Part Number: ADS131A04 Hello,
I reed a thread regarding problems with crystal startup. We have discovered that the XTAL input of the ADS131A04 is extremely sensitive.
We used the recommended crystal ABLS-16.384MHZ-L4Q-T, the crystal is placed very close…
Part Number: ADS131A04 Dear forum members,
Currently I'm designing a new product with an ADC in it. Previously I've had good experience with the ADS131A04 and it will fit the requirements for the new product as well. The only requirement that…
Part Number: ADS131A04 Hi team,
In 9.5.2.3.5, it said that "In synchronous slave mode, DRDY is an input signal that must be pulsed at the device set data rate", what does " device set data rate" means?
My understanding is that data…
Part Number: ADS131A04 Can someone please clarify if the Sinc3 digital filter of the ADS131A04IPBSR requires 3 conversion cycles to settle when the analog input has changed? If so, does it mean that to measure a staircase voltage waveform (as shown in…
Part Number: ADS131A04 Hi Team,
When power on again after aging test and power off, ADS131A04 output 0x400000,0,0,0 constantly; Then power off and power on again, output return to normal. Customer try to reproduce this abnormal output, but they failed…
Part Number: ADS131A04 Other Parts Discussed in Thread: ADS131A02
The data sheet for ADS131A0x states that the device responds with the READY word after reset: 0xFF02 for ADS131A02 and 0xFF04 for ADS131A04. However, if I send multiple NULL command frames…
Part Number: ADS131A04 Hi team,
My customer is considering the case using 8.192MHz external clock with 3.3V IOVDD even though the recommended value IOVDD >2.7V is 16.384MHz. Could you help me to answer the question below?
Q1. Why does the recommended…
Part Number: ADS131A04 Hello,
The sample holder sampled at a frequency of fMOD (4.096 MHz), which means the sampling time is only T_mod/2 (approximately 0.122uS), as described in ADS131A04 Manual 9.3.2 (as shown in the figure below). If the sampling capacitance…
Part Number: ADS131A04EVM Other Parts Discussed in Thread: ADS131A04 , This is my first time installing the delta sigma EVM SW on the PC and these are the screenshots of what I am seeing. The Device is unidentifiable but the SW states the HW is ready. I…
Part Number: ADS131A04 Hello,
ADS131A04 is delta-sigma (ΔΣ) ADC, is the S/H circuit same with SAR ADC? How to design the buffer circuit, is the same with SAR ADC?
In addition, the datasheet describes that ADS131A04 is simultaneous-sampling,…
