Low-Power Two-Channel Sensor  
Signal Processor  
General Description  
Features  
The MAX1463 is a highly integrated, low-power, two-  
channel sensor signal processor optimized for industri-  
al 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.  
o Programmable Amplification, Calibration,  
Linearization, and Temperature Compensation  
o Two Differential or Four Single-Ended Sensor  
Input Channels  
o Accommodates Sensor Output Sensitivities from  
1mV/V to 1V/V  
The MAX1463 accommodates sensors with outputs  
ranging from 1mV/V to 1V/V and supports both pro-  
grammable current and voltage sensor excitation. The  
MAX1463 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.  
o Two DAC/PWM Output Signal Channels  
o 4–20mA Output Capability  
o 4kB of FLASH Memory for Code and Coefficients  
o 128 Bytes of FLASH Memory for User Information  
o Integrated Temperature Sensor  
o Flexible Dual Op-Amp Blocks  
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 for buffering the DAC outputs, driving  
heavier external loads, or providing additional gain and  
filtering.  
o Programmable Sensor Input Gain and Offset  
o Programmable Sensor Sampling Rate and  
Resolution  
o Programmable Current Excitation Source for  
Bridge Sensors  
o Buffered 1.25V Output Reference  
The MAX1463 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.  
o No External Trim Components Required
