1 Values in this table are based on test with limited matrix samples in lab environment.

2 Typical values assume Temp = 25 °C and fACLK = Max, unless otherwise stated. Typical values are for reference only, and are

not tested in production.

3 This resistance is external to the SoC. To achieve the best results, the analog source resistance must be kept as low as

possible. The results in this data sheet were derived from a system that had < 15 Ω analog source resistance.

4 See Figure 35, "Sample time VS. RAS".

5 1 LSB = (VREFH - VREFL) / 2^N, N = 12

6 ADC conversion clock at max frequency and using linear histogram.

7 No missing code

8 Input data used for test is 1 kHz sine wave.

9 Measured at VREFH = 1.68 V and pwrsel = 2.

10 ENOB can be lower than shown, if an ADC channel corrupts other ADC channels through capacitive coupling. This coupling

may be dominated by board parasitics. Care must be taken not to corrupt the desired channel being measured. This coupling

becomes worse at higher analog frequencies and with switching waveforms due to the harmonic content.
