MAX1452AAE+

The MAX1452AAE+ is an integrated analog-sensor signal processor from Analog Devices, optimized for industrial and process control applications using resistive element sensors. It provides amplification, calibration, and temperature compensation, enabling performance close to the sensor's inherent repeatability.

This device features a fully analog signal path, eliminating quantization noise. It supports digitally controlled trimming with integrated 16-bit DACs for offset and span calibration, allowing for truly interchangeable sensor products. The architecture includes programmable sensor excitation, a 16-step programmable-gain amplifier (PGA), internal EEPROM, four 16-bit DACs, an uncommitted op amp, and an on-chip temperature sensor.

The MAX1452AAE+ operates from a supply voltage of 4.5V to 5.5V with a typical current consumption of 2mA. It is designed for a wide operating temperature range of -40°C to 125°C. The component is available in a 16-SSOP package, suitable for surface mounting.

Key features include a single-chip, integrated analog signal path that reduces design time and saves space. It accommodates sensor output sensitivities from 4mV/V to 60mV/V and supports single-pin digital programming. The device offers 16-bit offset and span calibration resolution and supports both current and voltage bridge excitation.
