Analog Devices / Maxim Integrated MAX1454 Sensor Signal Conditioning Device
Analog Devices MAX1454 Precision Sensor Signal Conditioners provide amplification, calibration, and temperature compensation and will accommodate sensor output sensitivities from 1mV/V to 200mV/V. The fully analog signal path of the MAX1454 Precision Sensor Signal Conditioners introduces no quantization noise in the output signal while enabling digitally controlled trimming of the output and offset. Span is calibrated with integrated 16-bit DACs. Applications for Analog Devices MAX1454 Precision Sensor Signal Conditioners include pressure sensors, strain gauges, pressure calibrators and controllers, resistive element sensors, and humidity sensors.
