The MAX1454 is a highly integrated analog sensor
signal conditioner targeted for automotive applications.
The device provides amplification, calibration, and temperature compensation to 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 of the output. Offset and span are calibrated
with integrated 16-bit DACs, allowing sensors to be truly
interchangeable.
The device architecture includes a programmable sensor excitation, a 32-step programmable-gain amplifier
(PGA), a 2K x 8 bits internal flash memory, four 16-bit
DACs, and an on-chip temperature sensor. In addition
to offset and span compensation, the device provides a
unique temperature-compensation method for offset TC
and FSO TC to provide a remarkable degree of flexibility
while minimizing manufacturing costs
