The MAX1455 is a highly integrated, sensor signal processor for resistive element sensors. The MAX1455 provides amplification, calibration, and temperature compensation that 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 integrated 16-bit digital-to-analog converters (DACs). Offset and span are also calibrated using 16-bit DACs, allowing sensor products to be truly interchangeable.
The MAX1455 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 MAX1455 provides a unique temperature compensation strategy that was developed to provide a remarkable degree of flexibility while minimizing testing costs.
The MAX1455 is available in die form, and in 16-pin SSOP and TSSOP packages.
