TABLE 16-10: A/D CONVERTER CHARACTERISTICS: PIC16C745/765 (COMMERCIAL, INDUSTRIAL) Param No. Sym Characteristic Min Typ† Max Units Conditions A01 NR Resolution — — 8 bits bit A02 EABS Total Absolute error — — < ± 1 LSb VREF = VDD = 5.12V, VSS ≤ VAIN ≤ VREF A03 EIL Integral linearity error — — < ± 1 LSb VREF = VDD = 5.12V, VSS ≤ VAIN ≤ VREF A04 EDL Differential linearity error — — < ± 1 LSb VREF = VDD = 5.12V, VSS ≤ VAIN ≤ VREF A05 EFS Full scale error — — < ± 1 LSb VREF = VDD = 5.12V, VSS ≤ VAIN ≤ VREF A06 EOFF Offset error — — < ± 1 LSb VREF = VDD = 5.12V, VSS ≤ VAIN ≤ VREF A10 — Monotonicity (Note 3) — guaranteed — — VSS ≤ VAIN ≤ VREF A20 VREF Reference voltage 2.5V — VDD + 0.3 V A25 VAIN Analog input voltage VSS - 0.3 — VREF + 0.3 V A30 ZAIN Recommended impedance of analog voltage source — — 10.0 k Ω A40 IAD A/D conversion current (VDD) — 180 — µA Average current consump- tion when A/D is on. (Note 1) —90 — µA A50 IREF VREF input current (Note 2) 10 — — — 1000 10 µA µA During VAIN acquisition. Based on differential of VHOLD to VAIN to charge CHOLD, see Section 12.1. During A/D Conversion cycle * These parameters are characterized but not tested. † Data in “Typ” column is at 5V, 25 °C unless otherwise stated. These parameters are for design guidance only and are not tested. Note 1: When A/D is off, it will not consume any current other than minor leakage current. The power-down current spec includes any such leakage from the A/D module. 2: VREF current is from the RA3 pin or the VDD pin, whichever is selected as a reference input. 3: The A/D conversion result never decreases with an increase in the input voltage and has no missing codes. |
