1. Specified by design - Not tested in production.

2. Data valid up to 130 °C, with a 22 pF PCB capacitor, and VDDA = 1.6 V.

3. Slow channels correspond to all ADC inputs except for the fast channels.

RAIN (Ω)

Minimum sampling time (s)

Fast channel

Slow channel(3)

CLK

1. The sampling time defines the minimum sampling clock cycles (SMP) to be programmed in the ADC (refer to the product reference manual for details).

Sampling

(1)

Mux

Number of CLK clock cycles = ADC resolution / 2

Total conversion time: 0.5 +Tsamp + N/2

SMP

1/2
