2.3.7. Analog Input 0
Analog Input 0 is a 16-bit differential input that accepts a voltage in the range of ±10 volts with a resolution of
305 µVolts. Signals outside of this range may damage the input. To interface to a single-ended (non-
differential) voltage source, connect the signal common of the source to the negative input (pin 8, AIN 0-) and
the analog source signal to the positive input (pin 19, AIN 0+). A floating signal source should be referenced
to the signal common (pin 20, AGND) as shown in Figure 2-27.
