In the nRF5340 product specification version 1.2, I see an internal bandgap reference error range of -1.8/+0.5%.
- In the nRF5340 product specification version 1.2, I see an internal bandgap reference error range of -1.8/+0.5%.
- Is this the same internal reference used by the ADC?
- Is this the reference error over the recommended operating temperature range of the nRF5340?
- I see in older RF development zone cases, such as case ID: 268846, that the room temperature reference error is +-0.2%. Is this error still applicable to the nRF5340
- How stable is the reference error over time?
- The nRF5340 product specification also lists gain errors from -3% to +3% (+4% for G=0.5, G=1)
- Is this the gain error over the recommended operating temperature range of the nRF5340?
- How stable is the gain error over time?
- Are gain values < 1 realized by tap points on the resistor ladder?
- If we use a gain value < 1, is there an additional series source resistance that we have to account for when calculating minimum ADC acquisition time?
