General Description
The MAX1455 is a highly integrated automotive analog-
sensor signal processor for resistive element sensors.
The MAX1455 provides amplification, calibration, and
temperature compensation that enable 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 integrated 16-bit digi-
tal-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 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 MAX1455 provides a unique tem-
perature compensation strategy that was developed to
provide a remarkable degree of flexibility while minimiz-
ing testing costs.
The MAX1455 is available in die form, 16-pin SSOP and
TSSOP packages.
Customization
Maxim can customize the MAX1455 for high-volume
dedicated applications. Using our dedicated cell library
of more than 2000 sensor-specific function blocks,
Maxim can quickly provide a modified MAX1455 solu-
tion. Contact Maxim for further information.
