The MAX12900 has an optimal combination of features to enable and enhance the next generation of 4mA - 20mA transmitters. A low 250µA current consumption increases the current available for the microcontroller and enables added enhanced features to be included in the sensor or actuator. A 10ppm/°C maximum reference drift and a 0.005% linearity improve system accuracy over a wide temperature range. Ten key building blocks are integrated into a small 5mm x 5mm TQFN package that enables smaller transmitter form factor for 4mA - 20mA loops. The MAX12900EVKIT implements a complete 4mA - 20mA PIR transmitter sequence to evaluate the system performance and to use it as a reference design for projects.
