PIN CONFIGURATION
The SMD1102, SMD1103 and SMD1113 each contain a
10-Bit data acquisition system (DAS) with dedicated EE-
PROM alarm limit storage. The three devices communi-
cate with the host μP via a standard two-wire I

C serial
interface. After initialization the SMD1102/1103/1113 can

automatically monitor one or more analog input channels.
If any input signal moves beyond its user-programmed
limits the host is notified by the SMB
ALERT
#
output, enabling
fault prediction in telecom line card applications, as an
example.
