AD15700
CIRCUIT OPERATION
The AD15700 contains precision components for interfacing
analog I/O to a processor. Configuration for particular applications
can be made with short external interconnects under the device.
TYPICAL CONNECTION DIAGRAM
Figure 4 shows how, using a minimum of external devices, the com-
ponents within the AD15700 can be interconnected to form a
complete analog interface to a processor. The circuit implements signal
conditioning that includes buffering, filtering, and voltage scaling.
