The MAX1464 is a highly integrated, low-power, low-noise multichannel sensor signal processor optimized for indus- trial, and process-control applications such as pressure sensing and compensation, RTD and thermocouple lin- earization, weight sensing and classification, and remote process monitoring with limit indication. The MAX1464 accepts sensors with either single-ended or differential outputs. The MAX1464 accommodates sen- sor output sensitivities from 1mV/V to 1V/V. The MAX1464 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 each signal and temperature. Uncommitted op amps are available to buffer the DAC outputs, drive heavier external loads, or provide additional gain and filtering. The MAX1464 incorporates a 16-bit CPU, user-pro- grammable 4kB of FLASH program memory, 128 bytes of FLASH user information, one 16-bit ADC, two 16-bit DACs, two 12-bit PWM digital outputs, four rail-to-rail op amps, one SPIā„¢-compatible interface, two GPIOs, and one on-chip temperature sensor. The MAX1464 operates from a single 5.0V (typ) supply and is packaged for automotive, industrial, and commer- cial temperature ranges in a 28-pin SSOP package.
