For 4–20mA Loop Industrial Automation

April 24, 2018 – Mouser Electronics, Inc., the authorized global distributor with the newest semiconductors and electronic components, is now stocking the MAX12900 sensor transmitter analog front end (AFE) from Maxim Integrated. With ultra-low power consumption of just 170 µA (typical) and a 5 mm × 5

The Maxim MAX12900 sensor transmitter, available from Mouser Electronics, enables increased system accuracy with 10 ppm per degree Celsius voltage reference and 0.01 percent maximum error. The ultra-low power transmitter converts PWM data from a microcontroller into current over a 4 – 20 mA loop, supporting two-, three- and four-wire configurations.

The MAX12900 integrates ten building blocks to help engineers optimize functionality and performance: a low-dropout (LDO) regulator; two conditioner circuits for PWM inputs; two low-power, low-drift general-purpose operational amplifiers; a wide-bandwidth, zero-offset drift operational amplifier; two diagnostic comparators; power-up sequencer; and a low-drift voltage reference.

The MAX12900 sensor transmitter is supported by the MAX12900 evaluation kit, which includes an evaluation board and graphic user interface to enable USB communication between the target device and a PC. The transmitter is ideal for smart sensors and remote instrumentation in industrial automation and process control.
