Preliminary DS39544A-page 157 PIC16C925/926 TABLE 15-11: A/D CONVERTER CHARACTERISTICS: PIC16C925/926 (COMMERCIAL, INDUSTRIAL) PIC16LC925/926 (COMMERCIAL, INDUSTRIAL) Param No. Sym Characteristic Min Typ† Max Units Conditions A01 NR Resolution —— 10-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 —— < ± 2 LSb VREF = VDD = 5.12V, VSS ≤ VAIN ≤ VREF A07 EGN Gain error —— < ± 1 LSb VREF = VDD = 5.12V, VSS ≤ VAIN ≤ VREF A10 — Monotonicity — guaranteed —— VSS ≤ VAIN ≤ VREF A20 VREF Reference voltage AVDD - 2.5V — AVDD + 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) PIC16C925/926 — 220 — µA Average current consump- tion when A/D is on. (Note 1) PIC16LC925/926 — 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. During A/D Conversion cycle † 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 RA3 pin or VDD pin, whichever is selected as reference input. |
