Sorry bother you guys again, I have some questions about the AD7765 datasheet .
- On AD7765 datasheet Page 13, Figure 18, the "Normal Power Mode INL" picture, it use the percentage "%" as the unit for the INL, normally we will use LSB as the unit for INL, How to convert this percentage value to LSB value? Is equation below correct?
- INL LSB = percentage x FS / (Voltage per LSB)
- The AD775 contains an on-board differential amplifier, and the datasheet recommended us to use this amplifier to drive the ADC , I want to know the parameters or the specification in the datasheet was measured with the amplifier, or without the amplifier?
Thanks for help.
