Maxim’s ultra low-power MAX12900 sensor transmitter at Mouser Mouser Electronics is now stocking the MAX12900 sensor transmitter analog front end (AFE) from Maxim Integrated. With ultra-low power consumption of just 170 uA (typical) and a 5mm × 5mm footprint, the highly integrated sensor transmitter reduces space by up to 20 per cent and power up to 50 per cent compared with other 4–20mA loop products.

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

Maxim’s MAX12900 integrates 10 building blocks to help engineers optimise 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 suitable for smart sensors and remote instrumentation in industrial automation and process control.
