Preliminary DS39682C-page 327 PIC18F45J10 FAMILY TABLE 23-25: A/D CONVERSION REQUIREMENTS Param No. Symbol Characteristic Min Max Units Conditions 130 TAD A/D Clock Period 0.7 25.0(1) μsTOSC based, VREF ≥ 2.0V TBD 1 μs A/D RC mode 131 TCNV Conversion Time (not including acquisition time) (Note 2) 11 12 TAD 132 TACQ Acquisition Time (Note 3) 1.4 TBD — — μs μs -40 °C to +85°C 0 °C ≤ to ≤ +85°C 135 TSWC Switching Time from Convert → Sample — (Note 4) Legend: TBD = To Be Determined Note 1: The time of the A/D clock period is dependent on the device frequency and the TAD clock divider. 2: ADRES registers may be read on the following TCY cycle. 3: The time for the holding capacitor to acquire the “New” input voltage when the voltage changes full scale after the conversion (VDD to VSS or VSS to VDD). The source impedance (RS) on the input channels is 50 Ω. 4: On the following cycle of the device clock. |
