General Description
The MAX1464 is a highly integrated, low-power, low-
noise multichannel sensor signal processor optimized
for industrial, automotive, and process-control applica-
tions such as pressure sensing and compensation,
RTD and thermocouple linearization, 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
sensor output sensitivities from 1mV/V to 1V/V. The
MAX1464 provides amplification, calibration, signal lin-
earization, and temperature compensation that enable
an overall performance approaching the inherent
repeatability of the sensor without requiring any exter-
nal trim components.
Two 16-bit voltage-output DACs and two 12-bit PWMs
can be used to indicate each of the temperature-com-
pensated 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 SPI-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 com-
mercial temperature ranges in a 28-pin SSOP package.
