The MAX1312ECM+ is a easy-to-use, low-power isolated Analog to Digital Converter (ADC) with a 4-20mA industrial current loop transmitter. It features an isolated loop-powered ready-to-use bidirectional design that provides both isolated current output and isolated analog input from 0 to 20mA. This powerful ADC also provides precision current sensing with low noise, A/D conversion accuracy to ±2% of full-scale, and wide adjustable sampling rate range (10-500KHz). This unit is ideal for use in harsh industrial and environmental settings where superior performance, accuracy and cost are essential.

The MAX1312ECM+ is perfectly suited for applications such as current loop measurements, photoelectric sensors, Rotary encoders, pressure transducers, accelerometers, RTDs, and temperature/humidity sensors. The loop-powered interface allows the device to be hooked up directly to the transmitter without extra power sources, and eliminates the need to use complex and expensive isolation amplifiers. The unit\'s One-pack solution takes the hassle out of installing and configuring the unit, and it also features an integrated loop-powered transmitter that transmits a clean, low-noise output.

Operating on 4-20mA current-loop signals, the ADC is robust, versatile, and able to monitor and provide results with great accuracy. Its built-in twelve-bit ADC has a maximum sampling rate of 500kHz, and its wide input range permits sampling of signals from 0-20mA. The loop-powered transmitter allows for simple connection to the device and eliminates the need for an external power supply. Additionally, the device has an adjustable current isolation limit that allows users to set the limit to an optimal value that matches their needs.

The MAX1312ECM+’s analog input has a galvanic isolation up to 3500V, making the device certified for high voltages up to 4000V, perfect for environments with considerable electrical noise. This unit is optimized for low power consumption, utilizing a 0.5mA sample current, and its adjustable sample rate offers power savings by reducing sample rate when precision can be sacrificed.

The MAX1312ECM+ also features high noise immunity and EMC protection, making it suitable for electrical and electronic equipment exposed to high EMC levels. The unit includes a built-in low noise filter, which helps filter out unwanted noise from the analog signal. This additional feature ensures that the incoming signal has been processed and is free from any possible noise and distortion. Additionally, this unit provides a functional safety feature that helps protect both equipment and personnel.

The MAX1312ECM+ is a great choice for applications that require high accuracy, low power consumption, and isolation. With its easy-to-use design and its ability to monitor and provide accurate results, the unit is perfect for applications in the industrial and hazardous environments. The wide input range, high-voltage protection, low power requirement, and built-in features make this ADC an ideal solution for commercial and industrial applications.
