3.4. Analog Inputs (TB304)
The three I/O board analog inputs are16-bit differential inputs that accept a voltage in the range of ±10 volts
with a resolution of 305 µV. 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
N O T E : Analog Input 0 on the I/O board is tied to Analog Input 0 on J205 (see
you connect to all of the analog inputs in one place (do not connect to AIN0 at both TB304 and J205).
