MAX1452AAE+T

The MAX1452AAE+T is a low cost precision sensor signal conditioner in 16 pin SSOP package. This highly integrated analogue sensor signal processor utilizes resistive element sensors. The MAX1452 provides amplification, calibration and temperature compensation that enables an overall performance approaching inherent repeatability of sensor. The fully analogue signal path introduces no quantization noise in output signal while enabling digitally controlled trimming with integrated 16bit DACs. Offset and span are calibrated using 16bit DACs allowing sensor products to be truly interchangeable. The MAX1452 architecture includes programmable sensor excitation, 16 step programmable gain amplifier (PGA), 768byte (6144bits) internal EEPROM, four 16bit DACs, uncommitted op-amp and an on-chip temperature sensor. It is used in pressure sensors, transducers, transmitters, strain gauges, pressure calibrators and controllers, resistive elements sensors, accelerometers and humidity sensors.
