The MAX1452EVKIT-NS+ from Maxim Integrated Products is a MAX1452 evaluation kit. The MAX1452 is a highly integrated analogue-sensor signal processor optimized for industrial and process control applications utilizing resistive element sensors. The MAX1452 provides amplification, calibration and temperature compensation that enables an overall performance approaching the inherent repeatability of the sensor. The fully analogue signal path introduces no quantization noise in the output signal while enabling digitally controlled trimming with the integrated 16bit DACs. Offset and span is calibrated using 16bit DACs, allowing sensor products to be truly interchangeable. The MAX1452 architecture includes a programmable sensor excitation, a 16-step programmable-gain amplifier, a 768byte (6144bit) internal EEPROM, four 16-bit DACs, an uncommitted op amp and an on-chip temperature sensor.
