Table 5-18 lists the input conditions of the ADC. Table 5-18. ADC, Power Supply and Input Range Conditions Over operating free-air temperature range (unless otherwise noted) PARAMETER TEST CONDITIONS VCC MIN TYP MAX UNIT DVCC ADC supply voltage 2.0 3.6 V V(Ax) Analog input voltage range All ADC pins 0 DVCC V IADC Operating supply current into DVCC terminal, reference current not included, repeat-single-channel mode fADCCLK = 5 MHz, ADCON = 1, REFON = 0, SHT0 = 0, SHT1 = 0, ADCDIV = 0, ADCCONSEQx = 10b 2 V 185 µA 3 V 207 CI Input capacitance Only one terminal Ax can be selected at one time from the pad to the ADC capacitor array, including wiring and pad 2.2 V 2.5 3.5 pF RI Input MUX ON resistance DVCC = 2 V, 0 V = VAx = DVCC 2 kΩ Table 5-19 lists the timing parameters of the ADC. Table 5-19. ADC, 10-Bit Timing Parameters Over operating free-air temperature range (unless otherwise noted) 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 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. 2 V 1.5 µs 3 V 2.0 |
