Electrical Characteristics for the A/D Converter

(VCC

= AVCC = 3.0 V to 3.6 V, VSS = AVSS = 0 V, Ta = − 40 °C to + 85 °C)

*1 : Depending on the clock cycle supplied to peripheral resources.

Ensure that it satisfies the value; PCLK cycle

× more than 4 + the value calculated from (Equation 1).

The condition of the minimum conversion time is when PCLK

= 33 MHz, the value of sampling time: 0.424 μs,

external impedance: 1.4 k

Ω or less and compare time: 0.72 μs.
