MAX1463

19-2549; Rev 0a; 11/04 MAX1463 Low-Power Two-Channel Sensor Signal Processor General Description The MAX1463 is a highly integrated, low-power, twochannel sensor signal processor optimized for industrial and process control applications such as pressure sensing and compensation, RTD and thermal-couple linearization, weight sensing and classification, and remote process monitoring with limit indication. The MAX1463 accommodates sensors with outputs ranging from 1mV/V to 1V/V and supports both programmable current and voltage sensor excitation. The MAX1463 provides amplification, calibration, signal linearization, and temperature compensation that enable an overall performance approaching the inherent repeatability of the sensor without requiring any external trim components. Two 16-bit voltage output DACs and two 12-bit PWMs can be used to indicate each of the temperature-compensated sensor signals independently, as a sum or difference signal, or user-defined relationship between eac...
