(2) The internal reference current is supplied from terminal AVCC. Consumption is independent of the ADC10ON control bit, unless a conversion is active. The REFON bit enables to settle the built-in reference before starting an A/D conversion. (3) Calculated using the box method: (MAX(–40°C to 85°C) – MIN(–40°C to 85°C)) / MIN(–40°C to 85°C)/(85°C – (–40°C)). (4) The sensor current ISENSOR is consumed if (ADC10ON = 1 and REFON = 1) or (ADC10ON = 1 and INCH = 0Ah and sample signal is high). When REFON = 1, ISENSOR is already included in IREF+. (5) The temperature sensor offset can be significant. TI recommends a single-point calibration to minimize the offset error of the built-in temperature sensor. (6) The typical equivalent impedance of the sensor is 51 k Ω. The sample time required includes the sensor on-time tSENSOR(on). (7) The on-time tVMID(on) is included in the sampling time tVMID(sample); no additional on time is needed. (8) The condition is that the error in a conversion started after tREFON is less than ±0.5 LSB. 5.39 REF, Built-In Reference over recommended ranges of supply voltage and operating free-air temperature (unless otherwise noted) (1) PARAMETER TEST CONDITIONS VCC MIN TYP MAX UNIT VREF+ Positive built-in reference voltage REFVSEL = {2} for 2.5 V, REFON = 1 3 V 2.51 ±1.5% V REFVSEL = {1} for 2.0 V, REFON = 1 3 V 1.99 ±1.5% REFVSEL = {0} for 1.5 V, REFON = 1 2.2 V, 3 V 1.5 ±1.5% AVCC(min) AVCC minimum voltage, Positive built-in reference active REFVSEL = {0} for 1.5 V 1.8 V REFVSEL = {1} for 2.0 V 2.2 REFVSEL = {2} for 2.5 V 2.7 IREF+ Operating supply current into AVCC terminal(2) fADC10CLK = 5.0 MHz, REFON = 1, REFBURST = 0, REFVSEL = {2} for 2.5 V 3 V 18 24 µA fADC10CLK = 5.0 MHz, REFON = 1, REFBURST = 0, REFVSEL = {1} for 2.0 V 3 V 15.5 21 fADC10CLK = 5.0 MHz, REFON = 1, REFBURST = 0, REFVSEL = {0} for 1.5 V 3 V 13.5 21 TCREF+ Temperature coefficient of built-in reference(3) IVREF+ = 0 A, REFVSEL = {0, 1, 2}, REFON = 1 30 50 ppm/ °C ISENSOR Operating supply current into AVCC terminal(4) REFON = 0, INCH = 0Ah, ADC10ON = N/A, TA = 30°C 2.2 V 20 22 µA 3 V 20 22 VSENSOR See (5) ADC10ON = 1, INCH = 0Ah, TA = 30°C 2.2 V 770 mV 3 V 770 VMID AVCC divider at channel 11 ADC10ON = 1, INCH = 0Bh, VMID ≈ 0.5 × VAVCC 2.2 V 1.06 1.1 1.14 V 3 V 1.46 1.5 1.54 tSENSOR(sample) Sample time required if channel 10 is selected(6) ADC10ON = 1, INCH = 0Ah, Error of conversion result ≤ 1 LSB 30 µs tVMID(sample) Sample time required if channel 11 is selected(7) ADC10ON = 1, INCH = 0Bh, Error of conversion result ≤ 1 LSB 1 µs PSRR_DC Power supply rejection ratio (DC) AVCC = AVCC(min) to AVCC(max), TA = 25°C, REFVSEL = {0, 1, 2}, REFON = 1 120 µV/V PSRR_AC Power supply rejection ratio (AC) AVCC = AVCC(min) to AVCC(max), TA = 25°C, f = 1 kHz, ΔVpp = 100 mV, REFVSEL = {0, 1, 2}, REFON = 1 6.4 mV/V tSETTLE Settling time of reference voltage(8) AVCC = AVCC(min) to AVCC(max), REFVSEL = {0, 1, 2}, REFON = 0 → 1 75 µs |
