Prathmesh Kulkarni

Part Number: ADS8681
Other Parts Discussed in Thread: DRV5056,

Hi,

I am looking to use DRV5056 chip at 5V and taking its output to ADC to SPI chip.

Q1: Can i drive ADC to SPI -  AVDD at 5V and DVDD at 3V?

Q2: Will there be any constraints?

Q3: Is this typical way to tie 5V to 3V?if not, what would be the best option?

Q4: please suggest other chip, if required.

Thank You
