MAX1452 Sensor Signal Conditioner

Maxim's MAX1452 is a low-cost, precision analog-sensor signal conditioner

Image of Maxim Integrated's MAX1452 Sensor Signal ConditionerMaxim's MAX1452 is a highly-integrated, analog-sensor signal processor optimized for industrial and process control applications utilizing resistive element sensors. The MAX1452 provides amplification, calibration, and temperature compensation which enable an overall performance 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 interchangeable.

The MAX1452 architecture includes a programmable sensor excitation, a 16-step programmable-gain amplifier (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 temperature compensation strategy for offset TC and FSOTC, developed to provide a remarkable degree of flexibility while minimizing testing costs.

The MAX1452 is packaged for the commercial, industrial, and automotive temperature ranges in 16-pin SSOP/TSSOP and 24-pin TQFN packages.
