Note 1: Absolute accuracy refers to the accuracy of output code relative to the analog input including all error sources

(including quantization error) in an A/D converter, and is calculated using the equation below.

Absolute accuracy = output code - (analog input voltage ADiINn / 1 LSB)

When AVCC = AVREF = 3.072 V, 1 LSB = 3 mV.

Note 2: This refers to the input leakage current on ADiINn while the A/D converter remains idle.

Notes: • S&H stands for Sample and Hold

• It is A/D Conversion Characteristics when in BCLK mode and VCCE=VCC-BUS=VDDE=3.072V, VCCER=5.12V or

3.072V.
