Hello Zhenrong,
You may want to post a separate e2e thread specifically for the OPA827 or OPA828. The product team that supports these devices will be able to provide more insight into any 2nd and 3rd order settling time effects that these devices may…

Part Number: ADS127L21 Tool/software: Hello,
I have a few questions about the ADS127L21.
1) Was it written in the evaluation board datasheet and the ADS127L21 datasheet that internal clock is not recommended for AC voltage measurement. But we tested…
Part Number: ADS127L21 Other Parts Discussed in Thread: ADS1271 , ADS8900B Tool/software: Hi,
for a new project we need a 24Bit ADC without internal digital Filter (or bypass option) currently we use ADS127L21, but as we understand the digital filter is…
Part Number: ADS127L21 Other Parts Discussed in Thread: ADS127L11 Tool/software: Hi, We are working on a project on which we are planning to use ADS127L21 as ADC input. But I am facing issue with the Linux driver of ADS127L21 . Could someone please provide…
Part Number: ADS127L21 Tool/software: Hi Team
What is the SDO current drive capability? Is it 2mA
I need to connect the SDO to opto coupler and i need 6mA is it supported?
Thanks

Part Number: ADS127L21 Hi Team,
My customer has a question regarding ADS127L21 One-Shot Control Mode:
If One-Shot conversion is performed periodically, will there be latency through the filter for each conversion? Or is it just initial at the first measurement…
Part Number: ADS127L21 Other Parts Discussed in Thread: INA851 , TPS7A39 , REF3425 , TPS709 , REF6025 Hi TI Team
Im planning to use the ADS127L21 in combination with an INA851. I use a +/-5 V supply for the INA851 and a +/-2.5 V supply for the ADC via a TPS7A39…
Hello Cheol,
The THS4561 will correctly adjust the output common mode to the level needed by the ADS127L21 since the VCM output of the ADS127L21 is connected to the VCOM input of the THS4561. If the ADS127L21 is powered from +/-2.5V supplies, then the…
Part Number: ADS127L21 I am having trouble with the large input current of the IC.
AVDD1 = 5V AVDD2 = 5V AVSS = 0V REFP = 2.5V REFN = 0V IOVDD = 3.3V OSR 1024
AINP=4.5V Current 350uA AINN=0.5V Current 350uA
Since the input current is large as mentioned above…
