PRODUCTION DATA.
MIN | TYP | MAX | UNIT | ||
---|---|---|---|---|---|
ADCCLK (derived from PERx.SYSCLK) | 5 | 50 | MHz | ||
Sample window duration (set by ACQPS and PERx.SYSCLK)(1) | 320 | ns | |||
VREFHI | 2.4 | 2.5 or 3.0 | VDDA | V | |
VREFLO | VSSA | 0 | VSSA | V | |
VREFHI – VREFLO | 2.4 | VDDA | V | ||
ADC input conversion range | VREFLO | VREFHI | V | ||
ADC input signal common mode voltage(2)(3) | VREFCM – 50 | VREFCM | VREFCM + 50 | mV |
NOTE
The ADC inputs should be kept below VDDA + 0.3 V during operation. If an ADC input exceeds this level, the VREF internal to the device may be disturbed, which can impact results for other ADC or DAC inputs using the same VREF.
