DS39927C-page 235 PIC24F16KA102 FAMILY TABLE 29-24: A/D MODULE SPECIFICATIONS A/D CHARACTERISTICS Standard Operating Conditions: 1.8V to 3.6V (unless otherwise stated) Operating temperature -40°C TA +85°C for Industrial -40°C TA +125°C for Extended Param No. Symbol Characteristic Min. Typ Max. Units Conditions Device Supply AD01 AVDD Module VDD Supply Greater of VDD – 0.3 or 1.8 — Lesser of VDD + 0.3 or 3.6 V AD02 AVSS Module VSS Supply VSS – 0.3 — VSS + 0.3 V Reference Inputs AD05 VREFH Reference Voltage High AVSS + 1.7 — AVDD V AD06 VREFL Reference Voltage Low AVSS —AVDD – 1.7 V AD07 VREF Absolute Reference Voltage AVSS – 0.3 — AVDD + 0.3 V AD08 IVREF Reference Voltage Input Current —— 200 AVREF+ = 3.3V; sampling —— 1.0 mA VREF+ = 3.3V; converting AD09 ZVREF Reference Input Impedance —10K — (Note 3) Analog Input AD10 VINH-VINL Full-Scale Input Span VREFL —VREFH V (Note 2) AD11 VIN Absolute Input Voltage AVSS – 0.3 — AVDD + 0.3 V AD12 VINL Absolute VINL Input Voltage AVSS – 0.3 AVDD/2 V AD17 RIN Recommended Impedance of Analog Voltage Source — — 2.5K 10-bit A/D Accuracy AD20b NR Resolution — 10 — bits AD21b INL Integral Nonlinearity — ±1 ±2 LSb VINL = AVSS = VREFL = 0V, AVDD = VREFH = 3V AD22b DNL Differential Nonlinearity — ±1 -1 +1.5 LSb VINL = AVSS = VREFL = 0V, AVDD = VREFH = 3V AD23b GERR Gain Error — ±1 ±3 LSb VINL = AVSS = VREFL = 0V, AVDD = VREFH = 3V AD24b EOFF Offset Error — ±1 ±2 LSb VINL = AVSS = VREFL = 0V, AVDD = VREFH = 3V AD25b Monotonicity — — — — (Note 1) Note 1: The A/D conversion result never decreases with an increase in the input voltage and has no missing codes. 2: Measurements are taken with external VREF+ and VREF- used as the A/D voltage reference. 3: Impedance during sampling is at 3.3V, 25°C. This parameter is for design guidance only and is not tested. |
