MAX12900 Ultra-Low-Power 4-20mA Sensor Transmitter

The MAX12900 is an ultra-low-power, highly integrated 4-20mA sensor transmitter. The MAX12900 integrates ten building blocks in a small package: a wide input supply voltage LDO, two conditioner circuits for pulse-widthmodulated (PWM) inputs, two low-power, low-drift, generalpurpose operational ampli.

MAX12900 Features

* Supply rail monitoring, output current readback, open circuit and failure detection are a few examples of diagnostic features. All these features, as well as ultra-low-power and high accuracy make the MAX12900 ideal for loop-powered smart sensor transmitters for industrial application. The MAX12900
