Electrical Characteristics
Table A-20. ADC Conversion Performance 5V range, RVA enabled
Supply voltage V_DDA =5.0 V, -40^oC < T_J < 150^oC. V_RH = 5.0V. f_ADCCLK = 0.25 .. 2MHz ¹
The values are tested to be valid with no PortAD/C output drivers switching simultaneous with conversions.

generated reference values..
3 _{Please note: although different in value, drift of vrh_int and vrl_int will go in the same direction.}
