MAX1478 Evaluation
____________________________________Development Kit
To expedite the development of MAX1478-based trans-
ducers and test systems, Maxim has produced the
MAX1478 evaluation kit (EV kit). First-time users of the
MAX1478 are strongly encouraged to use this kit. The
MAX1478 EV kit is designed to facilitate manual pro-
gramming of the MAX1478 and includes the following:
1) Evaluation Board with a silicon pressure sensor.
2) Design/Applications Manual, which describes in
detail the architecture and functionality of the
MAX1478. This manual was developed for test engi-
neers familiar with data acquisition of sensor data
and provides sensor compensation algorithms and
test procedures.
3) MAX1478 Communication Software, which enables
programming of the MAX1478 from a computer (IBM
compatible), one module at a time.
4) Interface Adapter and Cable, which allow the con-
nection of the evaluation board to a PC parallel port.
MAX1478 Pilot
_______________________________Production System
For volume applications, Maxim has developed a fully
automated pilot production system. The system con-
sists of the Maxim 14XXDASBOARD and one or more
14XXMUXBOARD modules, a DVM, an environmental
chamber, and a pressure controller. Only the
14XXDASBOARD and the 14XXMUXBOARD modules
are available through Maxim. The user must acquire the
