94 / 124 page  PIC16C72 Series DS39016A-page 94 Preliminary © 1998 Microchip Technology Inc. TABLE 13-12 A/D CONVERTER CHARACTERISTICS: PIC16C72/CR72-04 (Commercial, Industrial, Extended) PIC16C72/CR72-10 (Commercial, Industrial, Extended) PIC16C72/CR72-20 (Commercial, Industrial, Extended) PIC16LC72/LCR72-04 (Commercial, Industrial) Param No. Sym Characteristic Min Typ† Max Units Conditions A01 NR Resolution — — 8 bits bit VREF = VDD = 5.12V, VSS ≤ VAIN ≤ VREF 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 — 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) PIC16C72/CR72 — 180 — µA Average current con- sumption when A/D is on. (Note 1) PIC16LC72/LCR72 — 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 9.1. 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. Note 2: VREF current is from RA3 pin or VDD pin, whichever is selected as reference input. |
