MAX1464AAI+T

Sensor And Detector Interfaces Overview

The MAX1464AAI+T is a low-power, low-noise multichannel sensor signal processor in a 28-pin SSOP package. It operates from a single 5.0V supply with a range of 4.5V to 5.5V and supports an industrial temperature range of -40°C to +125°C. The device integrates a 16-bit CPU, 4kB FLASH memory, a 16-bit ADC, two 16-bit DACs, two 12-bit PWMs, four rail-to-rail op amps, and an SPI interface. It accommodates sensor sensitivities from 1mV/V to 1V/V with programmable gain up to 244 V/V.

Sensor And Detector Interfaces Feature Summary

• Integrated signal conditioning including programmable amplification, calibration, linearization, and temperature compensation without external trim components.
• Dual-channel analog input supporting either two differential or four single-ended connections for versatile sensor interfacing.
• On-chip processing capabilities featuring a 16-bit CPU and non-volatile memory for executing user-defined algorithms locally.

Sensor And Detector Interfaces Applications

• Pressure Sensor Signal Conditioning
• Weight Measurement Systems
• Thermocouple and RTD Linearization

Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix '+T' against official documentation to confirm tape-and-reel packaging status. Confirm that the AAI variant meets the required -40°C to +125°C operating temperature range for your application environment. Ensure compatibility with the 28-pin SSOP footprint during PCB layout.

Sensor And Detector Interfaces Selection Notes

Select this component when high integration is required for sensor signal processing tasks involving pressure, weight, or thermal measurements. It is suitable for applications needing on-chip linearization and temperature compensation to reduce external component count. Verify that the 5V supply voltage aligns with the system power architecture.

Sensor And Detector Interfaces Part Context

The MAX1464 series includes variants such as the CAI (commercial), EAI (extended), and AAI (automotive/industrial) temperature grades. All share the same 28-pin SSOP package and functional block diagram. The AAI designation specifically denotes the extended temperature capability required for harsh environments.

Sensor And Detector Interfaces Replacement Considerations

Direct replacements within the same family include MAX1464CAI and MAX1464EAI, provided the temperature range requirements are met. Cross-family substitutes require verification of pinout compatibility and register-level software migration efforts.
