Note 1: Divide the frequency if f(XIN) exceeds 10 MHz, and make

φAD equal to or lower than 10 MHz.

Table 1.26.5. D-A conversion characteristics (referenced to VCC = 5V, VSS = AVSS = 0V, VREF = 5V

at Ta = 25oC, f(XIN) = 16MHZ unless otherwise specified)

Note 1: 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.

Note 2: When the Vref is unconnected at the A-D control register, IVREF is sent. When not using D-A

converter, with the D-A register for the unused D-A converter set to “0016”, so that prevent dissipation

of unnecessary reference power supply current.
