MAX1457 Evaluation
___________________ Development Kit
To expedite the development of MAX1457-based trans-
ducers and test systems, Maxim has produced a
MAX1457 evaluation kit (EV kit). First-time users of the
MAX1457 are strongly encouraged to use this kit.
The kit is designed to facilitate manual programming of
the MAX1457 with a sensor. It includes the following:
1) Evaluation board (EV board) with a silicon pressure
sensor, ready for customer evaluation.
2) Design/applications manual, which describes in detail
the architecture and functionality of the MAX1457.
This manual was developed for test engineers familiar
with data acquisition of sensor data and provides
sensor-compensation algorithms and test proce-
dures.
3) MAX1457 communication software, which enables
programming of the MAX1457 from a computer key-
board (IBM compatible), one module at a time.
4) Interface adapter and cable, which allows the con-
nection of the EV board to a PC parallel port.
