4 – 20 mA sensor transmitter

21 March 2018 Analogue, Mixed Signal, LSI

Applications for Maxim Integrated Products’ MAX12900 4 – 20 mA sensor transmitter include industrial automation and process control, loop-powered 4 – 20 mA current transmitters, remote instrumentation and smart sensors.

It increases system accuracy with 10 ppm/°C voltage reference and packs 10 optimised building blocks into its 5 x 5 mm package. The integration of a high-voltage LDO and power sequencing capability simplifies the powering up of the 4 – 20 mA sensor transmitter. Its reduced current consumption for low power requires just 250 μA of current maximum, and it enables system cost savings by converting pulse width modulation data from a microcontroller into current over a 4 – 20 mA loop with two-, three- or four-wire configurations.
