MAX1452ATG+T

Sensor And Detector Interfaces Overview

The MAX1452ATG+T is a precision sensor signal conditioner in a 24-pin TQFN package, rated for -40°C to +125°C. It operates on a single 5V supply with typical current consumption of 2.5mA. The device features a fully analog signal path with a 16-step programmable-gain amplifier (PGA) providing gain from 39V/V to 234V/V. It includes four 16-bit DACs for offset and span calibration, an uncommitted op amp, and 768 bytes of internal EEPROM. The output supports formats including 4–20mA, 0 to +5V, and ratiometric signals.

Sensor And Detector Interfaces Feature Summary

• Single-chip integrated analog signal path reduces design time by providing amplification, calibration, and temperature compensation without external trim components.
• Fully analog architecture introduces no quantization noise while enabling digitally controlled trimming via integrated 16-bit DACs.
• On-chip lookup table supports multipoint calibration and temperature correction to improve system performance across wide temperature ranges.
• Secure-Lock feature prevents data corruption of sensor coefficients after calibration.

Sensor And Detector Interfaces Applications

• Pressure Sensors
• Transducers and Transmitters
• Strain Gauges
• Resistive Elements Sensors

Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix ATG+T corresponds to the 24-pin TQFN-EP package and industrial/automotive temperature range (-40°C to +125°C). Confirm RoHS compliance status as indicated by the '+' designation. Ensure the ordering quantity matches the manufacturer's standard reel packaging requirements for this specific part number variant.

Sensor And Detector Interfaces Selection Notes

Select the MAX1452ATG+T when a compact surface-mount solution is required for high-precision resistive sensor conditioning. This package variant is suitable for applications demanding operation up to +125°C. Verify that the 16-step PGA gain range and 16-bit DAC resolution meet the specific offset and span calibration requirements of the target sensor element.

Sensor And Detector Interfaces Part Context

The MAX1452 series serves as a low-cost, highly integrated analog-sensor signal processor optimized for industrial and process control applications. It replaces discrete solutions by combining amplification, calibration, and temperature compensation into a single chip. The ATG+T variant specifically utilizes the 24-pin TQFN package to accommodate higher pin counts or thermal requirements compared to the SSOP versions.

Sensor And Detector Interfaces Replacement Considerations

Direct replacements include other MAX1452 variants such as MAX1452AAE+ (16-pin SSOP) or MAX1452AUE+ (16-pin TSSOP), provided the PCB layout can accommodate the smaller package and pin count differences are managed.
