Electrical Characteristics for the A/D Converter
(VCC
= AVCC = 2.7 V to 3.6 V, VSS = AVSS = 0 V, Ta = 40 °C to + 85 °C)
*1 : It depends on the actual external load and the clock cycle supplied to peripheral resources. Make sure to satisfy
PCLK cycle
× 4 or over + below (Equation 1). The condition of minimum conversion time is the value when
PCLK
= 33 MHz, sampling time: 0.424 μs, external impedance: 1.4 kΩ or below, compare time: 0.72 μs.
*2 : The current when the CPU is in stop mode and the A/D converter is not operating.
*3 : Compare time = {(CT + 1)
× 10 + 4} × peripheral clock (PCLK) period. (CT indicates compare time setting bits.)
The condition of the minimum compare time is when CT = 1 and PCLK = 33 MHz.
