MAX1452 General Description
The MAX1452 is a highly integrated analog-sensor sig-nal processor optimized for industrial and process con-trol applications utilizing resistive element sensors.The MAX1452 provides amplification, calibration, and temperature compensation that enables an overall per-formance approaching the inherent repeatability of the sensor. The fully analog signal path introduces no quantization noise in the output signal while enabling digitally controlled trimming with the integrated 16-bit DACs. Offset and span are calibrated using 16-bit DACs, allowing sensor products to be truly inter-changeable.
The MAX1452 architecture includes a programmable sensor excitation, a 16-step programmable-gain ampli-fier (PGA), a 768-byte (6144 bits) internal EEPROM,four 16-bit DACs, an uncommitted op amp, and an on-chip temperature sensor. In addition to offset and span compensation. The MAX1452 provides a unique tem-perature compensation strategy for offset TC and FSOTC that was developed to provide a remarkable degree of flexibility while minimizing testing costs.
The MAX1452 is packaged for the commercial, industri-al, and automotive temperature ranges in 16-pin SSOP packages.
