General Description
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.
