Transfer Functions
Unipolar 0 to +5V Devices
Table 5 and Figure 12 show the offset binary transfer
function for the MAX1304/MAX1305/MAX1306 with a 0
to +5V input range. The full-scale input range (FSR) is
two times the voltage at REF. The internal +2.5V refer-
ence gives a +5V FSR, while an external +2V to +3V
reference allows an FSR of +4V to +6V, respectively.
Calculate the LSB size using:
which equals 1.22mV when using a 2.5V reference.
The input range is centered about V
MSV
, internally set
to +2.5V. For a custom midscale voltage, drive REF
MS
with an external voltage source and MSV will follow
REF
MS
. Noise present on MSV or REF
MS
directly cou-
ples into the ADC result. Use a precision, low-drift volt-
age reference with adequate bypassing to prevent MSV
from degrading ADC performance. For maximum FSR,
do not violate the absolute maximum voltage ratings of
the analog inputs when choosing MSV.
Determine the input voltage as a function of V
