Notes:
Reference “L” side set permanently to AV
SS
, and reference “H” side set permanently to AV
CC
. As AV
CC
decreases, relative error increases.
Please use the output impedance of the external analog input circuit under the following conditions :
External circuit output impedance
≤
10 k
An overly high external circuit output impedance could cause a lack of analog voltage sampling time.
