Maxim MAX1455 Manual

19-1032; Rev 0; 5/08

General Description

The MAX1455 evaluation kit (EV kit) demonstrates resis-
tive element sensor compensation and calibration using
the MAX1455 and a computer. The kit includes an
assembled and tested PCB, which is available with a
factory-calibrated sensor (MAX1455EVKIT-CS) or with-
out a sensor (MAX1455EVKIT-NS). The software and
computer are not required for performing the initial per-
formance evaluation of the sensor option since the EV
kit is already compensated. A 10-pin ribbon cable con-
nects the EV board to a serial-key adapter,
MAX1452KEY, that plugs into a computer serial port,
allowing the board to be evaluated inside an environ-
mental chamber. The software requires a PC compati-
®
ble with Windows 95/98/2000/XP.
