Notes :
The L reference voltage is fixed to AV
SS
. The relative error increases as AVR becomes smaller.
Ensure that the output impedance of the external circuit connected to the analog input meets the following
condition :
Output impedance of external circuit
10 k
(Sampling Time
=
4.0
μ
s)
If the output impedance of the external circuit is too high, the analog voltage sampling time may be too short.
