with ±10V, ±5V, and 0 to +5V Analog Input Ranges
______________________________________________________________________________________

The input range is centered about V
MSV
. Normally,
MSV = AGND, and the input is symmetrical about zero.
For a custom midscale voltage, drive MSV with an
external voltage source. Noise present on MSV directly
couples into the ADC result. Use a precision, low-drift
voltage reference with adequate bypassing to prevent
MSV from degrading ADC performance. For maximum
FSR, be careful not to violate the absolute maximum
voltage ratings of the analog inputs when choosing
V
MSV
. Determine the input voltage as a function of
V
REF
, V
MSV
, and the output code in decimal using the
following equation:
Unipolar 0 to +5V Devices
Table 7 and Figure 11 show the offset binary transfer
function for the MAX1316/MAX1317/MAX1318 with a 0
to +5V input range. The FSR is two times the voltage at
REF. The internal +2.500V reference gives a +5V FSR,
while an external +2V to +3V reference allows an FSR
of +4V to +6V, respectively. Calculate the LSB size
using the following equation:
This equals 0.3052mV when using the internal reference.
