Linearity error of digital output N =

VNT - {1LSB × (N - 1) + VOT}

[LSB]

1LSB

Differential linearity error of digital output N =

V(N + 1) T - VNT

- 1 LSB [LSB]

1LSB

1LSB =

VFST - VOT

[V]

VOT: Voltage at which the digital output changes from “000H” to “001 H”.

VFST: Voltage at which the digital output changes from “3FE H” to “3FF H”.

Notes on Using A/D Converter

• External impedance values of the external input of 4.2 kΩ or lower (sampling time = 1.2 μs@ machine clock of 16 MHz) are

recommended. When the external impedance is too high, the sampling time for analog voltages may not be sufficient. In this

case, it is recommended to connect the capacitor (approx. 0.1 μF) to the analog input pin.
