4.2.1. Analog Input 1 (TB201)
Analog input 1 is differential and buffered by a precision unity gain differential AD622
instrumentation amplifier and converted to digital by a 12-bit ADS7816 analog to digital
converter allowing an input voltage in the range of +/- 10 volts. This produces a
resolution of 4.88 millivolts per bit of the A/D. Refer to Figure 4-2. To interface to a
single-ended (non-differential) voltage, ground the negative (-) input and connect your
signal to the positive (+) input. Analog input 0 is available at J104, see section 3.1.5. The
analog input has a 10 Giga-ohm input impedance.
