(1) Zero Offset Error : deviation of voltage input from ideal voltage to get the 00 code.
(2) Differential Non linearity : maximum deviation of the analog span of each output code from its ideal 1lsb value.
(3) Integral Non linearity : deviation of the ADC transfer curve from the ideal transfer curve, defined according to the
best straight line fit method.
(4) Gain Error : Deviation of voltage input from ideal value to get the highest code.
(5) Signal-to-noise plus distortion ratio (SINAD) : ratio between the RMS magnitude of the fundamental input
frequency to the RMS magnitude of all other A/D output signals.
(6) Total harmonic distortion (THD) : ratio of the RMS sum of all harmonics of the input signal (below one half of the
sample rate) to the fundamental.
(7) All inputs are 5V tolerant.
(8) IOH, IOL = ±4mA only for pins : SACLK, OCLK, SDA, SCL_0, SDA_0.
