The maximum recommended impedance for ana-

Equation 12-1 may be used. This equation assumes
that 1/2 LSb error is used (512 steps for the A/D). The
1/2 LSb error is the maximum error allowed for the A/D
to meet its specified resolution.
To calculate the minimum acquisition time, T

Manual (DS33023). In general, however, given a max
of 10k and a worst case temperature of 100°C, T
will be no more than 16µsec.
