0.1%-Accurate Signal Conditioner
for Piezoresistive Sensor Compensation
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
2) Design/applications manual, which describes in detail
3) MAX1457 communication software, which enables
4) Interface adapter and cable, which allows the con-
