Table 1.21.4. Electrical characteristics (referenced to VCC = 5V, VSS = 0V at Ta = 25oC, f(XIN)=10MHZ
unless otherwise specified)
Table 1.21.6. D-A conversion characteristics (referenced to VCC = AVCC =VREF =5V, VSS = AVSS =
0V at Ta = 25oC, f(XIN) = 10MHZ unless otherwise specified)
Note: This applies when using one D-A converter, with the D-A register for the unused D-A converter set to “0016”.
The A-D converter's ladder resistance is not included.
Also, when the Vref is unconnected at the A-D control register, IVREF is sent.
