PARAMETER | TEST CONDITIONS | VCC | MIN | TYP | MAX | UNIT | |
---|---|---|---|---|---|---|---|
fADCCLK | For specified performance of ADC linearity parameters | 2 V to 3.6 V | 0.45 | 5 | 5.5 | MHz | |
fADCOSC | Internal ADC oscillator (MODOSC) | ADCDIV = 0, fADCCLK = fADCOSC | 2 V to 3.6 V | 3.8 | 4.8 | 5.8 | MHz |
tCONVERT | Conversion time | REFON = 0, Internal oscillator, 10 ADCCLK cycles, 10-bit mode, fADCOSC = 4.5 MHz to 5.5 MHz | 2 V to 3.6 V | 2.18 | 2.67 | µs | |
External fADCCLK from ACLK, MCLK, or SMCLK, ADCSSEL ≠ 0 | 2 V to 3.6 V | 12 × 1 / fADCCLK | |||||
tADCON | Turnon settling time of the ADC | The error in a conversion started after tADCON is less than ±0.5 LSB. Reference and input signal are already settled. | 100 | ns | |||
tSample | Sampling time | RS = 1000 Ω, RI = 36000 Ω, CI = 3.5 pF. Approximately 8 Tau (t) are required for an error of less than ±0.5 LSB.(1) | 3 V | 2.0 | µs |
