Circuit Cellar Issue 188 Cantrell Table 1

Table 1—Exploiting over-sampling, the QF4A512 12-bit ADC can achieve 16-bit ADC performance (e.g., 13 to 13.5 ENOB is typical for a true 16-bit ADC) at lower sampling rates.

Sample rate	SINAD	ENOB
2 kHz	81 dB	13.2
20 kHz	80 dB	13
200 kHz	76 dB	12.3
2 MHz	69 db	11.2
