Forum Post: RE: ADC128S102-SEP: ADC128S102-SEP Digital Input Power Sequencing
Hi Aidan, I was able to take a look at this a little more this week. The digital IO pins actually do share the same protection circuitry of that of the digital supply, so the absolute max ratings...

Hi Takanori-san, Equivalent in what way? There is not a pin to pin device that would support reads, but we do have other I2C devices that support reads. Can you share what specs are most important and...
View ArticleForum Post: RE: ADS127L11: Unipolar mode: Vref, AVIN, AVDD1, AVSS.
Hello Bakul, The ADS127L11 has no register configuration for unipolar or bipolar mode. You can configure the supply voltages for unipolar (AVSS=0V, AVDD1=5V) or bipolar (AVSS=-2.5V, AVDD1=+2.5V), but...

Sorry for the delay here. Your commands are correct, you just need to look at 'the next' sequence to get the device ID. Here is a screen shot that should help. I sent 0xD002FFFA followed by 0xC8020000...
