MAX1452CAE+

MAX1452CAE+ is a low-cost precision sensor signal conditioner. It is a highly integrated analogue-sensor signal processor optimized for industrial and process control applications utilizing resistive element sensors. It provides amplification, calibration, and temperature compensation that enables an overall performance approaching the inherent repeatability of the sensor. The fully analogue signal path introduces no quantization noise in the output signal while enabling digitally controlled trimming with the integrated 16bit DACs. Offset and span are calibrated using 16bit DACs, allowing sensor products to be truly interchangeable. It is used in applications such as pressure sensors, transducers and transmitters, strain gauges, pressure calibrators and controllers, resistive elements sensors, accelerometers, and humidity sensors.
