4–20mA sensor transmitter improves system accuracy for industrial automation applications

February 12, 2018 Jamie Leland

Maxim Integrated Products, Inc. has introduced the MAX12900 ultra-low power, highly integrated 4–20mA sensor transmitter. Ideal applications include industrial automation and process control, loop-powered 4–20mA current transmitters, remote instrumentation, and smart sensors.

The 5 mm x 5 mm MAX12900 increases system accuracy with 10ppm/℃ voltage reference and adds an integrated high voltage LDO and power sequencing capability. Its reduced current consumption for low power requires just 250µA of current maximum. The new MAX12900 converts pulse width modulation data from a microcontroller into current over a 4–20mA loop with two, three, or four wire configurations. The MAX12900 is available in a 32-pin TQFN package and operates over an industrial temperature range of -40℃ to +125℃.
