For part re-use I would like to bypass INTVCC with the same 4.7uF ceramic cap as EXTVCC, but the datasheet calls out 2.2uF. Is this exact value needed to e.g. run an ADC, or is anything in the range of 2.2uF OK? Thanks!
INTVCC is used to power up the internal IC and driver circuit. The ceramic capacitor is used to provide a stable and to filter the ripple. 2.2uF is not the exact value needs to be follow. Larger value is OK. Thank you.
