Table A-17. ATD Conversion Performance 5V range
Table A-18. ATD Conversion Performance 3.3V range
Conditions are shown in Table A-4. unless otherwise noted. VREF = VRH - VRL = 5.12V. fATDCLK = 8.3MHz The values are tested to be valid with no PortAD output drivers switching simultaneous with conversions.
Num C
Rating1 ,2
1 The 8-bit and 10-bit mode operation is structurally tested in production test. Absolute values are tested in 12-bit mode.
2 Better performance is possible using specially designed multi-layer PCBs or averaging techniques.
