Evaluation Kit for the MAX1455

Buy Now View Details

Features and Benefits

Proven PCB Layout
Convenient On-Board Test Points
Fully Assembled and Tested
Optional Pressure Sensor (MAX1455EVKIT-CS)
Factory-Calibrated Over Temperature (MAX1455EVKIT-CS)
LabVIEW®-Based Software

Product Details

The MAX1455 evaluation kit (EV kit) demonstrates resistive 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 without a sensor (MAX1455EVKIT-NS). The software and computer are not required for performing the initial performance evaluation of the sensor option since the EV kit is already compensated. A 10-pin ribbon cable connects the EV board to a serial-key adapter, MAX1452KEY, that plugs into a computer serial port, allowing the board to be evaluated inside an environmental chamber. The software requires a PC compatible with Windows® 95/98/2000/XP.

Applications

Accelerometer Measurements
Humidity Sensors
MR and GMR Sensors
Piezoresistive Silicon Sensors
Pressure Sensors and Transducers
Resistive Elements Sensors
Strain Gauges
