MAX1452ATG+

Sensor And Detector Interfaces Overview

The MAX1452ATG+ is a highly integrated analog-sensor signal processor optimized for industrial and process control applications utilizing resistive element sensors. It provides amplification, calibration, and temperature compensation to enable overall performance approaching the inherent repeatability of the sensor. The fully analog signal path introduces no quantization noise while enabling digitally controlled trimming with integrated 16-bit DACs. Key electrical parameters include a supply voltage (VDD) of 4.5V to 5.5V, typical supply current of 2.5mA, and an oscillator frequency of 1MHz. The device features a 16-step programmable-gain amplifier (PGA) with differential signal-gain ranging from 39V/V to 234V/V. It includes a 768-byte internal EEPROM, four 16-bit DACs, and operates over a temperature range of -40°C to +125°C in a 24-pin TQFN-EP package.

Sensor And Detector Interfaces Procurement Notes

Verify the specific ordering suffix ATG+ corresponds to the 24-pin TQFN-EP package and -40°C to +125°C temperature range as documented in the official Analog Devices/Maxim Integrated datasheet. Confirm that the component meets RoHS compliance standards indicated by the plus sign in the part number. Ensure compatibility with the required serial digital interface communication protocol during integration.

Sensor And Detector Interfaces Selection Notes

Select the MAX1452ATG+ when high precision sensor signal conditioning is required for resistive element sensors such as pressure transducers or strain gauges. The 24-pin TQFN-EP package offers thermal advantages for industrial environments. Consider the low 2.5mA supply current for battery-operated or loop-powered applications requiring minimal power consumption.

Sensor And Detector Interfaces Part Context

The MAX1452 series serves as a low-cost precision sensor signal conditioner designed to simplify the design of complete precision sensor solutions. The ATG+ variant specifically utilizes a 24-pin Thin Quad Flatpack No-leads (TQFN) package with an exposed pad, suitable for surface-mount assembly. This package option supports the industrial and automotive temperature ranges alongside the commercial and standard industrial SSOP/TSSOP variants.
