3.3. Analog Input 1
On ML amplifiers, Analog Input 1 is a 16-bit differential input that accepts a voltage in the range of ±10 volts
with a resolution of 305 µVolts.
On MPamplifiers, Analog Input 1 is a 12-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, and the analog source signal to the
positive input. A floating signal source should be referenced to the signal common (pin 1, AGND) as shown
in Figure 3-7.
