Part Number: ADS8405 1. Is there any requirements for the power sequencing of ADS8405 since there are two power supplies (VA and VDB) ? I can't find any information about that in the datasheet.
2. Can I place capacitors on REFOUT pin even if I use…
Hi, We use an ADS8405i in the design and for some boards we can't get fullscale input for the ADC. It saturates near 1V instead of 4V. I have verified the Vref that is exactly 4.096V and the 5V is OK. I just see a small ripple of 150 mV on the 3.3V for…
Hello Bonnie, Thank you for your reply! I am sorry for the so late response, got back to this project! My application concerns exciting and reading temperatures from 11 different NTC's, converting readings to 16 bit data and sending it to 28335 DSP. …
Other Parts Discussed in Thread: ADS8405 , ADS8406 , THS4031 Hi:
I have many legacy boards that use an 16-bit ADS8401 sampling at 1 MHz that is performing poorly as far as its SNR. The PDS says SNRAD of the ADS8401 is about 85dB. In our legacy system, it…
