Note 1. The reference power supply current is included in the power supply current value for D/A conversion.

Note 2. When the MCU is in Software Standby mode or the MSTPCRD.MSTPD16 (ADC120 module-stop bit) is in the module-stop state.

Table 2.14

Rising and falling gradient and ripple frequency characteristics

Conditions: VCC = AVCC0 = 1.6 to 5.5 V

The ripple voltage must meet the allowable ripple frequency fr(VCC) within the range between the VCC upper limit (5.5 V) and lower limit (1.6

V).

When the VCC change exceeds VCC ± 10%, the allowable voltage change rising and falling gradient dt/dVCC must be met.
