(Continued)
*4: This defines the power supply current when the A/D converter is not in operation and the CPU is stopped
(at “VCC = AVCC = AVRH = 5.0 V”)
*5 : When FCP is 20 MHz : tSMP
= (Rext + Rin) × Cin × 7 = ST × CLKP cycle = 21h × 50 ns = 1.65 μs.
*6 : When FCP is 20 MHz : tCMP
= CKIN × 11 = CT × CLKP cycle × 11 = 4 h × 50 ns × 11 = 2.2 μs.
*7 : This represents the conversion time per channel when tSMP and tCMP are selected while FCP is 20 MHz.
Analog Input Equivalent Circuit
Notes:
As AVRH becomes smaller, the error becomes greater.
Use the output impedance rS of the external circuit for analog input under the following conditions :
Output impedance rS of the external circuit = 4 k
Ω (Max)
If the output impedance of the external circuit is too high, the sampling time of the analog voltage may
not be sufficient.
When placing a DC blocking capacitor between the external circuit and input pin, set the capacitance to
the value calculated by multiplying CSH by several thousands as a guideline in order to minimize the
impact from dividing voltage capacitance with CSH.

= approx. 2.5 kΩ (5 V ± 10%)
CSH
= approx. 8.5 pF
Note: These element parameters should be regarded as tentative values used only for design purposes.
