1 The range is from 1.71 V to 1.89 V.

2 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. The RAS and

CAS time constant should be kept to < 1 ns.

3 See Figure 33, "Sample time VS. RAS".

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

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

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